The effect, called quantum entanglement, has been observed before, but never with such large amounts of matter. Don't expect transporters next week, but it is interesting that this report hits the streets the same day that Enterprise debuts."

I don't know about that. With functional teleportaion and a little hacking, teens could probably swap breasts or other body parts. The questions is can you supply raw material and recreate an object if the pattern is still in the buffer or some other storage a la replication. I guess replication is just one step beyond teleportation. The next question is who owns the rights to your data as it's being transmitted? Do data streams have rights?

melquiades (314628) | about 13 years ago | (#2355141)

As I've understood these experiments in the past, entanglement involes splitting a particle, or taking two existing particles, and "entangling" their states -- so that, for example, if you change the spin of one electron, its partner electron's spin also changes, even at a great distance (or something to this effect).

The application to faster-than-light information transmission is obvious. But teleportation? The article doesn't give enough specifics. Can anybody shed light on this? How would this experiment lead to a teleporter??

Re:Clarification...? (0, Redundant)

de Selby (167520) | about 13 years ago | (#2355214)

I've read that while the entanglement works without delay, information isn't transmitted at more than the speed of light.

But I have now idea why.

Re:Clarification...? (3, Interesting)

|_uke (158930) | about 13 years ago | (#2355356)

The information does not travel through time/space. There is a direct link between the entangled particles so there is no travel involved. (Think of an indirect link as anything that requires travel, which means things like radio/light/etc anything used in todays form of communication.) Because of this, you are not traveling faster than light.

Of course the exact details of how this works I could not tell you.

The thing I love about this however, is not the practical uses here on earth. But accross space. We could have live internet connections between mars and earth, for example.

Another cool thing, instead of using any of the standard methods of connecting to an isp, you buy a 'node' from an isp you wish to use. From then on, reguardless of your location, you can use that node to connect through the isp's network. This means you could have a nice chat while sitting in your home on mars.

Interesting though... I wonder how differences in time/space between entangled particles would effect things...

If you travel near the speed of light, while communicating with someone through an entangled pair to someone who is on earth... What happens?

Will the modifications made to the entangled particle be reletive to the first particle?

hrm... suppose so... wow that would be weird.. LOL

I think their goal may be practical to quantum computing. I could explain this here, but I already did it here [gmu.edu] . Basically, you need to be able to create a quantum copier to create a quantum computer. Building a quantum copier is difficult because, due to the no-cloning theorem, arbitrary quantum states cannot be copied perfectly every time. You can either clone a subset of quantum states perfectly or you can copy arbitrary states with a certain probability of failure.

Re:Clarification...? (3, Insightful)

lkcl (517947) | about 13 years ago | (#2355290)

regarding teleportation. it's simple. when you fire one photon at another, they interact [they're waves, but also particles]. in this way, you get one photon passing through another, or you get one photon imparting "mass" to another photon, and a change of direction of the two photons, conserving momentum. when you fire one photon at an "entangled" pair, if the momentums are matched, then the "fired" photon can actually disappear at the location where it hits one of the "entangled" pair, and reappear at the location of the SECOND "entangled" pair. in this way, you have instant teleportation - of photons. now make that many photons, and you have instantaneous quantum communication it's not really FTL because it's actually the same photon that happens to have more than one point-of-presence in the physical universe. now, step that up to particles, instead of just photons, and you have instantaneous teleportation. however, i theorise that this would require some _seriously_ cohesive photons, which probably implies that they must have intelligence built-in to the photons, and it's at the word "intelligence" as associated with "photons" that i diverge from current "accepted" theories regarding the nature of the universe and i'm going to shut up because there is a lot more to learn than meets the eye.

A Clarification... (5, Informative)

HEbGb (6544) | about 13 years ago | (#2355310)

Clarification:

Quantum entanglement involves creating a system in which the state (polarization, spin, etc.) of two or more particles are 'dependent on' each other. Measuring the state of one particle defines the state of the other, 'magically', over some distance.

HOWEVER make no mistake, nothing in quantum mechanics or entanglement theory allows anything resembling faster-than-light information traveling, nor teleportation as we understand it. This is pure fantasy that many physicists subtly or not-so-subtly use to solicit grants, or at least popular press. (There's plenty of this nonsense in sci-tech magazines.) It certainly worked here.

Here's another example of macroscopic 'quantum entanglement'. I have a bag with two billiard balls, one black, one white. I close my eyes, pull one out and put it in a second bag. Then, I hand you the first bag, and walk across the room with the second bag, and open it. Once I look at the color of the billiard ball in my bag, the color of the ball in your bag 'magically' changes color and assumes a defined state. These billiard balls are entangled, very much like subatomic particles are.

Can you ever transport information faster than light using this method? NO. Can matter be teleported? NO. I really wish these pop-sci articles would put an end to these misconceptions once and for all...

Re:A Clarification... (4, Insightful)

jaoswald (63789) | about 13 years ago | (#2355358)

It doesn't necessarily "change the state" of the second particle. (It can't, since the particles cannot causally interact; the particle's state evolves according to the local environment). However, the results of measurements on the second particle are inter-dependent with the results of the measurements of the first particle, even though the acts of measurement themselves cannot be connected causally (in the sense of special relativity).

The really funky thing is that the *choice* made to determine what kind of measurement to make on the first particle affects the inter-dependence. The idea being that "somehow" the measurement apparatus is communicating its setup to the distant particle, even though it really can't. This is really disturbing, but probably doesn't have any better explanation than "that's just how it is."

Re:A Clarification... (4, Insightful)

renard (94190) | about 13 years ago | (#2355417)

Your billiard ball example is equivalent to Einstein's "hidden variables" attempt to explain away quantum entanglement. Bell's theorem demonstrated that the predictions of quantum mechanics were actually inconsistent with such a theory - and subsequent experiments proved him right. The universe is far more mysterious than you or Einstein give it credit for.

In fact the reproduction of a quantum state - in all its particulars - is as perfect a teleportation as we might ever expect to achieve - see my accompanying comment. So I don't think your criticisms are entirely justified.

I say "not entirely" because extrapolating 13 orders of magnitude, and to real systems rather than super-cooled ones - as required for useful teleportation - still requires a bit of hutzpah. But the scientists cannot take all the blame. After all, the Trekkies were there long before...

Your clarification is only partially correct. Under some very limited conditions, superluminal (faster-than-light) speeds are possible. I remember reading about this in The Dancing Wu Li Masters [amazon.com] (very good overview of relativity for the non-physics types out there). A quick search for "superluminal" in your favorite search engine will generate links such as this Scientific American [sciam.com] article about the very limited conditions necessary for superluminal speeds.

a_hofmann (253827) | about 13 years ago | (#2355348)

You are right, this quantum teleportation allows the transfer of particle states over distance. This is not about transporting matter. This will not allow us to build teleporters.

jms (11418) | about 13 years ago | (#2355411)

I've always thought that an interesting science fiction scenario would be a future where teleportation is a day-to-day part of life, but instead of actually teleporting people to the new location, the equipment creates a new copy of the person at the new location, then destroys the old copy of the person at the original location, a minor detail of the teleportation process that is, of course, a well kept secret.

In this scenario, people happily teleport to work, vacation, the grocery store every day, never realizing that every time they step into a teleporter, "their" life comes to an agonizing end ...

until one person finds out ...

Any good examples of this scenario in "classic" sci-fi? I can't imagine I'm the first to think of it, but I've never actually run into it in my reading, and I haven't run into it in recent sci-fi either.

Re:Clarification...? (1)

Mythias (27496) | about 13 years ago | (#2355477)

This exact same scenario took place in an Outer Limits episode that I saw. The process involved making a copy and transporting that copy to another place, then destroying the original. But, as is standard Outer Limits fare, something went wrong and the transfer was unsuccessful. Therefore, the original was not destroyed. The next day they found out that the transfer WAS successful, but was reported incorrectly. So they had to destroy the orignal AFTER she'd already woken up and was told what happened. I'm not explaining it very well, but it was a good episode.

Re:Clarification...? (2, Informative)

mocm (141920) | about 13 years ago | (#2355354)

You don't change their spin, you measure it and find that it is the same. Usually you measure a quantity that has a fifty fifty chance to give one or the other result. The interesting thing is that it always comes out the same for the entangled particles. No matter how far their separation in time and space.

You can't convey any information that way since you don't know what the result of the measurement will be. But somehow the particles "know".

Re:Clarification...? (5, Informative)

renard (94190) | about 13 years ago | (#2355364)

Can anybody shed light on this? How would this experiment lead to a teleporter??

Well, this will get us into some of the most dangerous neighborhoods of quantum mechanics, but I'll see what I can do.

The quantum entanglement of two particles means that (just as you say) the behavior of one particle becomes perfectly correlated with the behavior of another. In the classic example case, two photons are generated with opposite polarizations. If you can transmit them a distance apart without any interference, then the photons will remain entangled, and a measurement of the polarization of one photon will have immediate implications for the polarization of the other.

Although this is very useful for quantum cryptography [lanl.gov] , please note that it will NOT allow you to transmit information any faster than the speed of light. To take the cryptographic example, it allows you to generate a safe one-time pad, known to both sides and to no one else, but you still have to transmit your actual message separately.

How can quantum entanglement be used for something like teleportation? Well, let us agree first that if I can produce a perfect quantum replica of a distant system, that is equivalent to teleporting the system. Any given electron (for example) is indistinguishable (in a very deep sense) from every other electron in the universe. So for teleportation all we need to do is reproduce a quantum state. You might say it's more akin to a quantum xerox machine than to most people's classical idea of teleportation.

Okay, so here's how it works: take your two quantum-entangled photons, and instead of simply measuring the polarization of the one nearby, get it to interact with a "target photon" that you want to teleport. If you set things up properly, and observe the outcome very carefully, then the interaction of the two photons on your end will cause the entangled photon - an arbitrary distance away - to enter a new state which is perfectly correlated with the state that your target photon had. Then, once you tell your distant collaborator about the exact outcome of the photon interaction on your side, your collaborator will be able to apply that knowledge to her entangled photon, and produce an exact quantum replica of your original target photon. Voila! Teleportation.

Note again that no faster-than-light communication is enabled by this. You still have to communicate a regular light-speed message between collaborators to get this to work. The actual experiment was carried out several years ago and is old hat by now. The current experiment improves upon previous efforts by entangling so many more (trillions!) particles.

The quantum entanglement of so many particles makes the actual teleportation of a similar number feasible, but one final note - even trillions of particles is many orders of magnitude less than the 10^27 or so particles in your average Starship Captain.

dragons_flight (515217) | about 13 years ago | (#2355374)

Here is a relatively straight forward discussion [ibm.com] of the theory behind teleportation via quantum entanglement.

Whether information transfer is actually instaneous is a hotly debated topic in the relevant circles. General relativity forbids anything (including information) from going faster than the speed of light. The standard formulation of quantum mechanics absolutely requires non-localized information (ie knowing about two spatial seperated points simultaneously). This is just symptomatic of the fact that neither is a complete theory yet, and we still have interesting things left to learn about how the universe truly works.

I'm amazed that this worked with "trillions" of atoms; this kind of phenomenon is usually restricted to very small, very energetic particles. But it's NOT teleporation. Teleportation involves taking an object from point A and moving it to point Z without crossing the in-between space, C through Y. This is like taking an object from point A, running it through the world's biggest and best Fax machine, then putting the result at point Z, without crossing C through Y.

Still, it's an interesting and ground-breaking result, one that (I hope) will make it past the peer review process, which kills more scientific papers than anything else.

This is incorrect. Classical teleportation is defined as a scenario where the sender is given the classical description of an arbitrary quantum state while the receiver simulates any measurement on it. This is exactly what you argues it isn't. Besides, if the destinction you make is one worth making or not is an open philosophical question, i.e. one that is not resolved.

It's what I've always said: we should have a new moderation cathegory - "Incorrect".

Guignol (159087) | about 13 years ago | (#2355368)

But what is an object ?
Is an object what it is made of ? (ie. the information of the object is the object) or is the object what it is itself ?
Does every single particle have an unknowable divine ID ?
If the object is completely described by its composition, then yeah teleportation might be possible, because it is directly related to the exchange of information.
But, for what I understand, the information exchange itself isn't specialy fast, you comunicate an experiment result by a normal mean.
The good thing is, you don't have to destroy any copy, the process involves destruction itself (of the original, and in fact, before the reconstruction).
You have a pair of entangled particles, A and B, as far away as you want them to be. you want to send a quantum state Q information from where A is, to where B is. incertainty priciple states that you cannot do this measurement without affecting the information itself, but, what you can do, is measure it against A (scrambling A and Q which is the destruction part you can't avoid). the result of this measure of Q against A can be transported anyway you like to B, and applied to it reconstructing the original Q state. it's like a XOR operation :)

This was also a concept in Micheal Critons(sp?) last book, "TimeLine". Quantum intanglement was perfected to allow individuals to cross over into other probabilities (ie: alternate universe theory). This could only be accomplished by destroying the existing object (person) in one universe and having it reassembled in another one. Slight impefections could creep in (random probabilities far greater from the norm of the universe they left) after many trips...much like over-faxing.

You're right in that it isn't true teleportation, but rather generating the right probabilities for an instance of matter to appear in another location. Sure it needs to be carried along a modulation-like system, but if you could increase the number of particles involved it will be quite impressive.

On those lines, many seem to think that Star Trek like teleportation just 'zoom', goes across space unhindered. But if you watch the shows, it would seem that the mechanism is similar, it sends the information through a modulated beam. Within the ship, the structure must have the ability to transfer this beam, hence they can beam around the ship (also note the frequency of the beam appears to be beyond visible range). As for beaming down to a planet, same thing. You notice they cant beam while their shields are up, because the carrier wave cannot pass the information through.

What the Star Trek teleporters have done is eliminate or reduce the amount of errors and changes in probablities that will arise after many, many, many teleports. The matter is effectively different after teleportation (random probability changes, but enough stay the same so that it still looks the same and exists in the same universe). I wonder what random changes they allow to matter in their teleporters; maybe you get hair that doesn't grow as fast anymore, or some other non-life threatening change.

TALL STORIES (BUT TRUE)

Because It Was There

When George Willig, a toy maker from Brooklyn, used homemade climbing equipment to scale the World Trade Center on a windy March day in 1977, he expected to be arrested when he reached the top, and he was. But Willig had not merely climbed what was then the tallest building in the world. Nor had he trespassed upon the property of the average New York commercial landlord. Willig had conquered the summit of a billion dollar, ten million square foot office complex built and run by the Port Authority of New York and New Jersey (PA), a bi-state planning agency charged with protecting public funds from diversion into speculative ventures.

But while Willig's stunt brought him instant popular acclaim, the Authority's higher-ups were not amused by the idea any sufficiently venturesome soul could turn the jewel in their real estate crown into an impromptu adventure park. The PA legal department pressed criminal trespass against Willig, then iced the cake with a $750,000 civil suit.

Keen to take up the cause of an underdog getting it in the neck from humorless bureaucrats, the local newsmedia rallied to Willig's support, mercilessly ridiculing the PA for failing to catch the spirit of a city universally renowned for its chutzpah. And besides, Willig had helped Gothamites forget, if only briefly, that New York was in the midst of its most severe fiscal crisis since the Great Depression. He had made them feel triumphant and unafraid. So it took a second publicity stunt, this one dreamed up by PA's top PR man, Sidney Frigand, to put a positive spin on the Authority's edifice complex.

Young Usama play's it safe (-1, Offtopic)

The beginnings of the bin Laden phenomenon are difficult to track down. The bin Laden family first appears when Sheik Mohammed bin Laden, a native of the Sunni Hadramout, emigrated from Yemen to Saudi Arabia in the 1960's. The clan appears to have gradually congealed power around itself, and forged a close relationship with the Saudi royal family, being granted all rights to construction of a religious nature, whether in Mecca, Medina or the Holy Palaces of Jerusalem (until 1967). The bin Ladens renovated Mecca after the royal house was highly satisfied with their work on the palaces. In any event, the bin Ladens established a financial empire that now reaches far beyond mere construction work. The bin Laden clan and the Saudi royal house soon had a very close working relationship, one not just based on finances, but on friendship and shared secrets as well. When young Usamah was growing up, he was ensconsed in the Saudi establishment, going to the same schools and colleges as the luminaries of the Arabian peninsula. Indeed, bin Ladens went to Victoria College in Alexandria, the Eton of the Middle East, where they rubbed shoulders with such excellencies as King Hussein of Jordan and Omar Sharif.

Usamah was born in 1957 in Riyadh. His father took many wifes, and young Usamah was born to one of the last and least respected of them. He was the 17th son of a reported 50 sired by Mohammed. Mohammed's brother and partner sired 50 more, making the bin Laden clan and influence huge. The fact that Usamah came to outshine them all is a testament to his innate genius.

Usamah as a young boy, on holiday in Sweden aged 14. His 'pale good looks' shone through already. Click here to view [adequacy.org] .

Earliest direct evidences of Usamah himself this reporter could track down are recollections by an old teacher, Brian Fyfield-Shayler. In 1969, whilst his decadent western peers were guzzling drugs and descending into an orgy of self, the callow bin Laden, just 13, was studying hard at Al-Thaghr, a school in Jeddah, Saudi Arabia modelled on the English public school system. Mr Fyfield-Shayler said (in this respected news source) "I remember him as quiet, retiring and rather shy. He was very courteous - more so than any of the others in his class. Physically, he was outstanding because he was taller, more handsome and fairer than most of the other boys. He also stood out as he was singularly gracious and polite, and had a great deal of inner confidence. He was very neat, very precise and very conscientious."

There can be no doubt that Usamah, an ordinary and pious young man, was deeply affected by his family's involvement in rebuilding the two holy Mosques in Mekkah and Madinah. We have already heard that his early teacher thought him a confident but reflective individual, so we shouldn't be surprised if he felt great pride that his family was involved in raising the glory of Allah in such spiritually significant places.

Throughout the 1970's Usamah spent his time studying and working for the family business. Doubtless he kept an eye on current affairs ? the disgraceful behaviour of Israel and America during this period is remarkable ? but he was determined to get his degree and be a credit to his family. In 1979 he graduated from King Abdul Aziz University in Jeddah with a degree in Civil Engineering.

BEGINNING OF THE LEGEND

Usamah as a handsome young man [adequacy.org] in the Mujahideen. Shortly after young Usamah graduated, the Soviet Union invaded Afghanistan to prop up the failing Communist regime. The Mujahideen put out an international call for help, and Usamah was inspired to leave the dusty world of commerce for more noble pursuits. He packed himself and several family bulldozers off to Afghanistan, and later was quoted as saying "In our religion, there is a special place in the Hereafter for those who participate in Jihad. One day in Afghanistan was like 1000 days of praying in an ordinary mosque."

Usamah made a huge difference to the Mujahideen. At first he was an effective politician and strategist. He recruited thousands of Arab fighters in the Gulf, paid for their passage to Afghanistan, and set up camps to train them. He designed defences along the Pakistani border, driving a bulldozer himself and taking great risks from Soviet helicopter gunship strafings as a result. Such was the personal stake he felt that before long he had taken up a Kalashnikov and was fighting on the front personally. This personal touch emerged again in 1986 when he and a few dozen Arab helpers fought off a Soviet onslaught in a small town called Jaji, near the Pakistani border. This ignited the Afghani resolve, as it was the first example that the Russians could actually be beaten. Just twelve months later he turned the tide of the Afghanistan war with a brilliant offensive against Soviet troops in the battle of Shaban. The Mujahideen suffered heavy casualties in the vicious, heavy fighting, but thanks to bin Laden's superb generalship the Soviets were pushed out of the area for good and the end was in sight for the Communists.

Hamza Mohammed, a Palestinian volunteer in Afghanistan, recalls "He was a hero to us because he was always on the Front Line, always moving ahead of everyone else. He not only gave his money, but he also gave himself. He came down from his palace to live with the Afghan peasants and the Arab fighters. He cooked with them, ate with them, dug trenches with them. That was Bin Laden's way."

By the late 1980's Usamah had established himself as a legend across all Afghanistan. It was at this time that his close personal friendship with the Taliban Mullah Mohammad Omar began. The Wahhabi brand of Islam they both share is somewhat similar to Protestantism, but in an Islamic context, and they are both very spiritual men. To this day they take reflective fishing trips in the backlands of their country, such is their binding friendship. Where the rest of the Islamic world has been corrupted by decadent Western ways, the Wahhabis stick to traditional Islam as taught in the Koran. They are amongst the very holiest and most pious of Muslims, their creed established in Saudi Arabia, to an extent, and also Afghanistan, which though not strictly a Wahhabi state is very closely modelled on one. A measure of his piety is that he selflessly rejected an offer from King Fahd of Saudi Arabia to expand the Prophet's mosque in Medinah. This cosy little deal would have pocketed Usamah a lovely $90 million, but he refused as he correctly recognised it as an attempt to lure him from Jihad against the communists.

RETURN TO THE HOMELAND

Usamah today, careworn and wise with experience. Usamah returned to Saudi Arabia in the late eighties, a celebrity throughout the Muslim world. Convinced by the words of the holy Koran, Usamah soon set aside his own personal, selfish best interests and began to campaign for the Saudi government to introduce Shariah (Islamic Law) and reduce its terrible corruption, an offence to Allah in the land of Mekkah. Although this was to get him into trouble with the corrupt authorities on several occasions, the real shakedown occurred when King Fahd decided to allow Western troops in the Kingdom during the Gulf War. Usamah criticised the Saudi regime for this terrible decision, and was promptly hounded with a harassment campaign. Before long, in 1991, he fled to the Sudan, and shortly afterwards was declared an outlaw by the Saudi regime, which stripped him of his nationality and put a price on his head. His loyalty to the word of the Koran and his conscience had cost him his home, and reduced him to a common bandit as far as his old circles in Saudi Arabia were concerned.

In the Sudan Usamah managed to expand his business interests considerably, and he continued his Jihad bankrolling. Always keeping a careful eye on ethical considerations, he made sure to only bankroll just causes, putting money on the underdog and the concept of right V might:

Chechnya. Here the Russians have sought to destroy all hope of Chechnian independance, but as usual bin Laden is involved, helping fund the Chechen guerrila fighters against the superior enemy. A noble cause.

Muslim Bosnians against the Serb overseers. Despite the justness of this cause, the US interfered, arresting the fighters he sent to help the cause of freedom against oppression. Nonetheless, bin Laden had a big impact there, as he does everywhere.

Palestine. bin Laden has always been outraged by the plight of the Palestinians. At a young age he came under the tutilege of a Palestininian man, Sheikh Abdallah Azzam, who was once a confidant of Yasser Arafat but had become disenchanted with the PLO. Some Usamah became intertwined with Palestinian politics and the cause.

Yemen. Usamah has long had links to the Yemen Wahhabi cause. He has also been involved in the struggle there - the bombing of the USS Cole was possibly an example of this (unlike the WTC, this bombing fits bin Laden's MO - the target was military, not involving innocent civilians.

Everyone of these causes was Just and right, and it is no wonder that Usamah's reputation only grew and prospered during this period ? and no wonder that an assassination attempt was made at this time, though he escaped with only some injuries.

AFGHANISTAN ONCE MORE

In 1996 Usamah moved permanently back to Afghanistan. In despair at the terrible situation in both Saudi Arabia and the Sudan, he sought a more traditional and devout setting. After Saudi Arabia decided to imprison Islamic scholars and hundreds of Mujahideen youths, after the rape of the Holy Land by the West and the occupation of the two Holy Places by American troops, Usamah decided to make a stand. He issued his first Bayan, or statement, 'A Declaration of War against the Americans Occupying the Land of the Two Holy Places'. This document was seminal, and simple ? a lucid warning instructing the Americans to leave the land of the two Holy Places or face military attack from the Mujahideen, the same Mujahideen that defeated the largest superpower in the world under his tutelage some few years before in Afghanistan.

"Muslims burn with anger at America. For its own good, America should leave [Saudi Arabia]."

Usamah is still in Afghanistan to this day. Despite the total lack of any evidence (The US claims to have evidence, but with it's usual broohaha is prepared to go to war rather than publically release it. It is so convincing they will give it to allies but not to the Taleban, from whom they expect an extradition with no evidence at all) relating him to the recent WTC attacks, he is castigated worldwide for this devilish act. Usamah may be no friend of the United States, and with good reason, but he has no record of attacking innocent civilian targets. He is an honourable man and an honourable fighter, with a long, proud record of fighting for the oppressed (but right) underdog.

So why must he die?

Because he must be martyred. It is my belief that Usamah has reached his peak. Already approaching his 50's, he can't continue his brave fight against Western imperialism forever. Already he is weakening, his judgement is failing and his body shrivels. Every Muslim who dies in Jihad is guaranteed a place in Heaven, and Usamah, in dying, can both guarantee his own elevation and strike a blow against the western imperial forces trying to paint him as some sort of extremist. If he martyrs himself, a thousand new and young Usamahs will be inspired by his legend and continue the good fight, and the truth about bin Laden will spread around the world, and so the simple peoples of this globe will hear of his valiant life and fight. When the Soviet Union invaded Afghanistan, the USA boycotted the Moscow Olympics, western opinion was outraged, and President Jimmy Carter embargoed all exports to the Soviet Union. Contrary to popular belief, the USA did not funnel military or financial support to the Mujahideen, however. In this interview bin Laden recalls "Personally neither I nor my brothers saw evidence of American help", so we see that the Americans were all mouth but had no guts. Now that America has, with it's usual hypocricy, decided to attack Afghanistan, it is clear that Usama must take risks to ensure maximum damage is applied to the enemy.

WHAT USAMAH MUST DO

Firstly he must provide tantalising glimpses of himself, drawing the Americans into Afghanistan. He must make sure the common people of Afghanistan understand that the Americans are out to culturally reprogram the Afghanis, one of the last pure peoples of the Earth. He must extract maximum damage upon the enemy in exchange for his own life. No superpower, however strong, can, once entered, come out of Afghanistan with honour. Hopefully the plight of Afghanistan and the indiscriminate killing of civilians that will occur there will reignite the Wahhabi cause throughout the Arab world, but especially in Pakistan and Saudi Arabia. There is a great, noble chance here for the Middle East to be reawakened in its old image.

Usamah made Afghanistan in his own image, it is thanks to his influence that it has steered a course away from the brutality and violence of communism, towards the status of a pure Muslim state. The Taliban, unlike the governments of Yemen, Iran and Saudi Arabia, is not corrupted by Western influence, and will not hand him over. The West knows it has a resolute enemy. Even in the unlikely even that they did decide to hand him over, they would be unnable to, and surely the Afghans would revolt and a new revolution would be needed.

The likelihood is that they shall be true to the tenets of Islam, and not hand over Usamah. Then, the US and other Western allies will be forced to invade Afghanistan, where they will meet a bloody end. Usamah must sacrifice himself in the process, for it is the best way of guaranteeing his place in heaven and exacting maximum pain upon the enemy.

Quantum Entanglement (3, Insightful)

blitz77 (518316) | about 13 years ago | (#2355225)

Quantum entanglement is basically splitting up a photon into 2 parts. These 2 parts are quantumly entangled, so when you measure one, you would get exactly the same result on the other as a result of them being entangled. The supposed ability to transport particles is not true. It is only able to allow measurements on one particle to be duplicated on the other. So, if we ever get this to work on large objects such as humans (!) you wont get teleported. There'd only be a duplicate of you on the other side. And in the act of measuring the state of all the particles of your body, you'd probably be dead too. I wouldnt care to have a duplicate of me on the other side, because you'd still be dead.

Re:Quantum Entanglement (2, Insightful)

DanEsparza (208103) | about 13 years ago | (#2355431)

You're funny.

While I would agree that this is the classic explanation of this phenomena I think it's important to point out that the photons can't be observed directly (like under a microscope) -- and we honestly don't know what the heck is going on at this point.

The article points out Einsteins famous quote describing this phenomena is "spooky action at a distance" -- which it is. I'm sure if you asked Schroedinger (spelling?) he'd tell you that the photon 'was neither split, nor one photon' ... because we just don't know.

If you want an interesting (although hardly scientific) read on this subject, check out Michael Chricton's 'Timeline' book.

Re:Quantum Entanglement (3, Interesting)

dragons_flight (515217) | about 13 years ago | (#2355446)

A) While isolating different parts of a particle's wave function is possible, this is rarely, if ever, what is meant by entanglement. Typically what is meant involves bringing multiple particles together and getting their wavefunctions to operate as a coherent entity, and maintaining this "coherence" after seperating the particles.

B) The measurement doesn't have to be the same (in fact quite often they respond by giving exactly opposite measurements). The only requirement is that they behave in a well defined correlated way predicted by Quantum Mechanics.

C) You are thinking of "fascimile copying" which is different from teleportation. In the first case you exchange information through entangled particles to create a close (but never perfect) duplicate of the original. In teleportation you destroy the state of the original to create an exact duplicate at the other end. This reference [ibm.com] provides a good explanation of the ideas behind teleportation.

D) Yes, you would have to entangle your whole body in order to teleport, but there are plenty of nondestructive ways to measure the body (think X-Rays), and it doesn't neccesarily follow that in some distant future there won't be a way to preserve at least one intact copy.

mmmmbeer (107215) | about 13 years ago | (#2355227)

I don't see how this would allow for teleportation. As many others have already mentioned, how do you draw a link between this and the ability to transport (or even duplicate) matter?

However, I do see a possibly very significant use of this technology. If you can maintain an entangled state between macroscopic objects, wouldn't this allow a change to one object to be seen immediately in the other? If so, couldn't this be used to create computer networking devices which would work over any distance without any delay, and without any necessary wires or similar infrastructure? This sounds like it could potentially create the "ansible" predicted by Ursula K. Le Guin and Orson Scott Card.

Teleportation of information, not teleportation of matter itself. You're right, the matter still has to get to its destination by standard processes. You'd need something like nanotech assemblers and scanners for teleportation:
  1. Get a bunch of raw materials, and a teleport receiver, to the teleport-to site.
  2. At the teleport-from site, scan the object to be "teleported" at an atomic (or maybe subatomic) level, possibly destroying it in the process.
  3. During the scan, transmit the scan's results to the teleport-to site, assembling a duplicate of the teleported object.

Re:Ansible (0)

Anonymous Coward | about 13 years ago | (#2355340)

You still cannot pass any information faster than light this way. Your problem is that a particle has an indefinite state before a measurement is conducted. Since you measure something, say the spin, the spin becomes defined once you measure it. Still you need to know when to determine the spin and this information you do not have and your measuring is going to affect the result. In short, no Tomorrows Slashdot News Yesterday, sorry.

Quantum Computing (4, Interesting)

cailloux (173392) | about 13 years ago | (#2355282)

One real posiblity for quantum entanglement would be in the area of quantum computing and distributed processing. The theory in a quantum computer is that every possible state of every computation can exist simultaneously. Only after you decide you want to know the answer to a specific problem will you find it - in effect any complex calculation is speeded up my magnitudes of order. In a distributed environment, quantum entanglement would allow for 2 (or more) quantum computers to join together and each work on a distributed/parallel process program and instantly share data, as well as solutions. For example, in gene research the refinement of proteins into useful medications could take place at a much faster rate because each quantum computer could "see" what the other got for evolutionary results and apply those changes along separate lines of reasoning while still being aware of what worked and what did not.

In a non-quantum computing environment, data networking could happen much faster (blowing the doors of gigabit ethernet) by being able to instantly transfer the entire contents of a hard drive from one place to the next along fiber; no longer are you sending electrons at high speed (c), but now you are transferring the entire data packet straight from one network card to the next.

As I understand Quantum Entanglement, you're not going to get teleportation with this. To create the initial entanglement, you have to perform an operation (such as shooting electrons with energy) to a pair of particles that are at the same inital location. The point of quantum entanglement is that once these particles are separated, the two particles still have this quantum connection between them.

But to get any transportation, you would need to put still need to transport(=move) one of those particles to the new location defeating the point of our transporter!

... is here [aps.org] . Sadly, just as you need a subscription to read the Nature article, you need a membership here, as well (or be willing to pay $15.00 via CC for an immediate download). You can't even get a preprint or tech report at Aarhus. Is it just me or are others starting to feel as if technical information, which was once disseminated for little or no cost, is now becoming increasingly expensive?


Oh well, welcome to the "Age of Access [ala.org] "...

the reason we "laugh" at Star Trek is because it does such a dippy, ignorant, bad job of recycling the world's sf ideas, dressed up in a sappy soap opera shell and performed by the worst actors the galaxy could muster. The idea of a teleporter was not originated on the damned program. Not that this is a teleporter anyway, at best it might someday offer some sort of "simultaneous" communications - like the Ansible from Le Guinn's The Dispossed.

Every time a remotely sf idea get mentioned on it some bloody fool comes along and blabs about the uncanny similarity to Star Trek..

SHUT UP! SHUT UP! SHUT UP! YOU ARE BORING EVERYBODY!

Destroy the Sun! (1, Informative)

"Since the beginning of time, man has yearned to destroy the sun"
-- J. Montgomery Burns


Ignoring the fact that this technology does not permit the transmission of matter, only information ...

If one could teleport matter, how much cadmium or other neutron absorber would one have to teleport into the sun in order to quench the nuclear reaction and make Burns' dream a reality? Or would it just not work at all?
