Diamonds Key To Quantum Computing

Soulskill posted more than 5 years ago | from the supercomputer-in-the-rough dept.

Supercomputing 92

I Don't Believe in Imaginary Property writes "Scientists P. Neumann, N. Mizuochi & co. have advanced quantum computing by finding a new method to get two-way and three-way, high quality quantum correlations that persist for hundreds or thousands of microseconds, even at room temperature. Their paper (subscription required) describes how they manipulated electrons from nitrogen vacancies in diamond using microwaves to entangle adjacent carbon-13 nuclei. Even better, this builds on previous results which indicate that diamonds with nitrogen impurities may be the key to creating useful quantum computing devices. The article provides a good description of what nitrogen vacancies are and why they prove useful."

Has anyone noticed that people are getting tired of all this quantum computing bullshit? Most of the posts below are just making fun of it all. QC is crap. Get over it. It is a big fucking lie that just refuses to go away as long as those fraudsters keep getting funding from us suckers, i.e., the public. I wish Slashdot would stop running stories about QC anymore. Only wild-eyed Star-Trek fanatics care and they don't count. Whoever promises to slash all funding for QC gets my vote in November. LOL.

O wow! how qualified! You know, i may be only 33 but i remember very well what people educated in the 60ties (e.g. Teachers, Engineers) told me when i was a child how transistors could NEVER replace tubes for certain applications (e.g. High power). Yea right. We see that now..... I work in the QC field, and we will not see any really working quantum computer doing any non-trivial task (i personally dont count dwaves "thermally assisted adiabatic QC" as one) the next 15 Years and after that it may take 30 Years or forever until it gets cheaper to buy QC instead of classical ones for the applications where QC are optimal. And even then it will not be in personal computers. But QC has the potential to replace very big computing systems (e.g. Blue Gene) which use a huge amoung of material and Energy for protein folding by a comparatatively decently sized QC which may take including the infrastructure (condensed matter QC: cooling, vacuum, shielding rooms, rf signal sources, staged amplifiers, crogenic electronics, optical/Atom/ion QC: cooling, lasers, optics, UHV equipment.) something well below 1MW, if you dont need big pumping Lasers more like a few kW, of power and less than 200 square meters (some of them will however need a tailored base of the building to avoid vibrations).

QC Is Crap Because It's Not Science (0)

Anonymous Coward | more than 5 years ago | (#23698727)

QC is based on a stupid conjecture (the Copenhagen interpretation of QM) that can never be observed. That is not science. It's voodoo crap, dead/alive cats and all that other jazz. Physicists don't even have a clue as to why quantum interactions are probabilistic and yet they feel qualified to conjecture that quantum states are superposed? Who you're fooling? Time travel believers and Star-Trek groupies maybe, but not anybody with more than two neurons between their ears. All the announcements we've been hearing about x qbits having been done in the lab are pure 100% bullshit. And you can take that to the bank.

In conclusion, DWave + David Deutsch = Snake oil salesmen. LOL.

Excuse me. QC is NOT based on the Copenhagen interpretation. If you dont understand that in a real experiment you have to split the Copenhagen interpreation into two parts. 1) The measurement process, during which you create a 'split' in the space of possivle paths which separates your systems more and more, while introdusing the coupling a way that you replace one of the conjugate variables by your own (i.e. random) information. 2) The Philosophical idea 'if the path are so well separated, do i have many realities (if i 'amplify action' really stronly)?'. The first question is what matters to physicist, and belive me, it is understood quite well. The second one does not fascinate me. Until we understand simple things perfectly, i wont think about more complicated things....

Who you're fucking kidding? That is exactly what it is based on: superposition of quantum states, which what the Copenhagen interpretation is about. You're a typical fraudster, a jackass, a liar, a con artist, a crook. You should give David Deutsch a call. But then again, maybe you are Deutsch. LOL.

Please do me a favor and read the following: http://en.wikipedia.org/wiki/Interpretation_of_quantum_mechanics#The_Copenhagen_interpretation [wikipedia.org] As it is said the Copenhagen interpretation is only an interpretation that we see QM systems in the way we see them. There are other approaches and as many people in the field and many who understood parts of Legget's work (and many other great people in the beginning of the 80s) I am not a fan of any theory requiring a wavefunction collapse or a concious observer role. And contrary to your assumptions superposition of Wavefunctions is NOT specific to the Copenhagen Interpretation, but a generic property of the QM we are using. And BTW i admire Deutsch, but not for the many-worlds interpretation (which does not qualify as a scientific theory because i can not make tests for it), but for his very solid work on infromation in QC.

I gather now with the ability to create diamonds in the lab, the need for quantum computers might force more people to make them.

hkmarks (1080097) | more than 5 years ago | (#23693945)

Natural diamonds are much more abundant than they'd have you believe. There's an artificial scarcity. Large, high quality diamonds are pretty rare, but there are plenty of small ones (enough to make tools out of them, and enough that diamond jewelery has next to no resale value.) The markup on new diamonds is huge and the supply chain is narrow.

Anyhow, isn't this whole thing the plot of the First Wave episode "The Apostles"? Except possibly without aliens? And probably fewer biker gangs?

As much as it's a cartel and as much as logic says otherwise, I'd easily get a diamond ring if she was so inclined. Believe it or not, for many that is as much a part of the marriage ceremony as the white dress, wows and all that. "A diamond is forever" is quite frankly probably the single best marketing slogan in history. There's rubies and saphires and emeralds and many other gemstones, but it placed diamonds in a category of its own and at the same time it exploits your own insecurity. No matter how much you think this is marketing BS from de Beers, she might not. Unless you're really, really sure she won't think you're cheap or sending subliminal messages or whatnot I'd just get the ring and eat that feeling of having been suckered. There's a time and place to take your battles in a marriage, and I think de Beers know damn well they picked one of those where it's not.

Re:Lab Made Diamonds (1)

SomeoneGotMyNick (200685) | more than 5 years ago | (#23708817)

My Wife has one diamond ring (a 1/10 carat engagement ring) and a 2 ct. tw. tennis bracelet.

I wouldn't want to marry someone who's materialistic to the point that a 1/10 carat real diamond isn't enough to carry tradition. The diamond tennis bracelet was a gift purchased from a windfall of income.

She likes the nice look of a diamond or CZ. In fact, she'd prefer a 2 ct. CZ over a 1/4 ct. real diamond because it looks better for a much lower price.

De Beers may have started a nice tradition with diamonds, but the act of offering a ring in contemplation of marriage never required a real diamond. More women should think that way.

Re:Why diamonds? (4, Informative)

$RANDOMLUSER (804576) | more than 5 years ago | (#23693783)

From TFA:

Carbon, the element which forms diamond, has four electrons available for bonding. To form diamond, the carbon atoms form a tetrahedral shape, where each carbon has four carbon neighbors, positioned evenly around the central atom. These atoms then share electrons, forming a very strong bond. If nitrogen is added during the formation of diamond, then some of the carbon positions will be taken by nitrogen. However, nitrogen has only three electrons available for bonding. Thus, every nitrogen atom is associated with a missing atom ^W electron in the tetrahedral. This imbalance leads to a very interesting situation, in which each vacancy is associated with a pair of electrons. In this case, the hardness of diamond is helpful because the atomic cores cannot move much, which helps preserve the quantum state of the electrons and nucleus. These robust quantum states are a necessary first step towards obtaining quantum computation.

Well I'm not sure about that, but there is an interesting co-incidence here, silicon is in the 4th group, and so is diamond(carbon).

  electrical(electronics) computers -> silicon
Quantum computers -> Diamonds (carbon)

we need to add impurities to silicon to get it to work the way we want it, these guys are adding impurities to carbon to get it to act the way they want.

The resemblance may be superficial but it is there, nature is symmetric after all.

Re:Why diamonds? (1)

GigaplexNZ (1233886) | more than 5 years ago | (#23699229)

It isn't a coincidence. It is standard semiconductor physics. You can mix an element from the 3rd group with an element from the 5th group together to make semiconductors as well, such as GaAs. Different types of dopant (impurities) determine whether the semiconductor is n-type or p-type. In this case, the Nitrogen atoms have an extra valence electron than Carbon creating an n-type doped semiconductor. Diamond would probably make a decent semiconductor for conventional computers as well, but it is far more expensive than silicon.

Re:Why diamonds? (1)

arktemplar (1060050) | more than 5 years ago | (#23699765)

Like your Sibling post had said, Diamond is tetrahedrally bonded carbon, it doesn't have that extra electron that makes 'graphite' a good conductor. Diamond here is not being used as a semiconductor from what I have understood (why I feel it cannot be used as one, not being one after all - I have written later).

You are correct about mixing 3rd group with 5th group but diamond (Carbon) is 4th group. notice however that you can mix 4th group with 5th group to give you your n type, which I already said still requires that the 4th group be a semiconductor which diamond is not.

I know about dopants etc. having spent four years in Electronics, however not being material sciences or something I may still be not completely correct. But thanks for the info any ways. Nitrogen has an extra electron but is also extra stable N_2 being almost inert (please notice the _almost_ ). I think it's cause of the strength of the tripple P-P orbital bonds.

Diamond would not at all make a good semiconductor for conventional computers the simplest reason being - Diamond is not a semiconductor, the more complete answer involving lots of quantum physics and me having to explain fermi levels. Please do check this out on wikipedia or some place (I'd suggest a book but I guess you may not have access to books on semiconductors unless you are an EE or in material sciences or something).

Science is above all else about building shared knowledge.

So quantum computing is science now? Has anybody ever observed superposed quantum states? I don't think so. QC is based on an unobserved interpretation of QM. It's based on a conjecture. It is not science as science is defined. And the fact that this crap is being published in peer-reviewed journals does not say much about the sanctity of peer review. When someone shows me a cat that is both alive and dead at the same time, I will believe in QC. Until then, it is just pure unmitigated hogwash and voodoo superstition.

Peer review is an incestuous mechanism whose purpose is to keep outsiders at bay. Science is thus immune to public criticism and ends up feeding on itself, producing monsters. Paul Feyerabend was right when he wrote in 'Against Method' that "the most stupid procedures and the most laughable results in their domain are surrounded with an aura of excellence. It is time to cut them down in size and give them a more modest position in society." Some so-called scientists should be ashamed of themselves.

I agree with you entirely. But note that while you are a graduate student (and undergrad too in most cases) you have access to 99.99% of all Journals through your universities resources (library, and online in my case). This is how it is in Canada anyway. I find it strange in general that they charge money. It must be for the corporations that have no academic ties and can afford to fork over the money. Anyway, information wants to be free. As far as I'm concerned, education should be free from Grade 1 to Post-Doctorate. This includes textbooks and journal papers.

Did you think that universities got all those academic journals for free? They have to pay for their subscriptions, same as anyone else.

Deciding on what subscriptions to pay for is a major part of research library management, and consumes a significant portion of the annual budget. Just because you get access included with your tuition/state funding/whatever doesn't mean it's cheap.

Anyway, it's not a no-cost proposition to run a journal, either. The fees aren't just a license to print money, although they may be higher than is completely justifiable. Still, a prestigious journal like Nature has a lot of overhead, relative to the readership. We're not talking about an issue of Newsweek that's going into every doctor's office in America. (It's one of the same reasons why textbooks cost more than, say, Harry Potter 7.)

You can make an argument that it can be done cheaper (or even for free), but it's harder to make the argument that the money is just wasted.

It's worse than that, actually.

Many of these leeches not only charge the reader, they charge the author to publish too.

But Google seems to either index _the _actual_content_ or has been SEO'd on every keyword very heavily - and yet you cannot actually read anything. This is very frustrating. As an ordinary internet user I feel like a second class citizen. Bugmenot is occasionally useful, but more often than not I simply find the exact paper I want to read but am fobidden from reading it.

Consequently I cite only sources that are actually available to the public and leave those who write for the gatekeepers of knowledge to obscurity.

Thankfully I am aware there is a growing backlash in all corners of the scientific community to boycott these journals and publish through publicly accessible sources. The problem is with certain orthodox institutions requiring publications in these archaic forms knowing they have sold out science. Hopefully they will also be swept aside in the years to come.

If you google search hard enough, you can usually find these papers free of charge from the originating university, either in the author's own website, or from a departmental archive.

I'm at an university, and even with a free Athens login from the campus library, our university still doesn't have a subscription to one or two of these companies. Basically, the subscription managers at the library will get a free trial or purchase a 1 years license with one of these companies. If enough papers are referenced, then the subscription is maintained, otherwise it is dropped.

Many research fields form their own cliques where they reference each others papers, and none from anybody else. If you are not in this clique, then it isn't worth taking out a subscription to that journal.

Fortunately, it is possible to get the jist of an unreadable paper by reading the descriptions from other papers.

That's the tricky part of running a research group - you want to publish your results in order get enough citations/references in other papers, in order to get further funding. But if you give away too much information, someone else can just set up a competing research department and take away your funding, so you end up having to start from scratch again.

So your survival tactic is to create a research group as large as possible to keep up the production of papers and the number of directions you can go in, or to investigate an area that nobody else has any interest in.

Having an expensive subscription for these research papers is one way to get the references, but reduce the risk of losing your funding.

i totally agree with you in principle, but like most things in life, without a financial incentive, there wouldn't be any scientific journals to publish in. who would run the journals - your tax-dollars? the researchers who publish in them? maybe some sort of advertising system would work... how annoying, though. good ideas are most welcome.

Some universities have policies that their professors should retain copyright if possible (and therefore post the papers on their own websites). If enough [big] universities push the issue, then hopefully the issue will get resolved.

However, it costs (according to Physical Review) more than $1000 to publish an article. There is a lot of typesetting, they might pay reviewers, and they have to be reliable.
Everyone at a university gets free access to the articles anyway, through their library proxy.
I've just written an assignment on a Phys. Rev article, actually, and did you know that you can now pay ~$1300 and make an article public?

I already knew that diamonds are the key to getting a three-way.

Why are diamonds still costly? (0)

Anonymous Coward | more than 5 years ago | (#23696541)

Ug, why are people thinking diamonds should be expensive anymore?

I know I'm posting this AC'ly, but hell I've seen diamond (brick sized) bricks produced out of that guy from the US Navy east coast plant.

What the fuck ever happened to him anyway - I kind of lost track. His techniques sure made artificial impurity free diamond easily enough, according to any test I ran anyway.

This was the major problem with the cartels - they were too damned pure according to various tests down to mass spectroscopy. He sure as hell seemed paranoid enough to avoid being 'dissapeared'.

Read it ages ago (long before the disappointing movie) but I seem to remember something about blue diamonds in the book "Congo" and the race to get them because they meant the fastest defense network or something like that? So that means Skynet will run on diamonds right?

The last paragraph of TFA is notable:

Provided the qubit state can be transfered to photonic qubits, then it should be possible to scale the entanglement up so that it can involve more than a single nitrogen vacancy "having the entanglement lasts for milliseconds helps in this regard. Furthermore, qubits based on nitrogen vacancies aren't too hard to scale, since it is a solid-state material "no vacuum pumps required, thank you very much. Finally, the longevity of the entanglement should also enable the development of a refreshable quantum RAM.

There are a bunch of different ways to represent a qubit, the fundamental unit of quantum computation. They all have advantages and disadvantages. I myself work with photonic qubits. Using photons it's actually considerably easier to get and hold coherence (high-quality quantum correlations) for as long as you need it than in other representations. But one of the problems with photons* is that they always travel at the speed of light (well der), and while that's great for communication, it's not so good if you actually want to store quantum information somewhere. So finding a good way to keep coherence for a reasonable length of time for something stationary is useful work.

*The other problem with photons is that they are relatively difficult to get to interact with each other. There are only a few situations where there is any appreciable interaction between two photons.

If this had happened a few years ago when I got married, I would have had reason to demand a diamond as well. "But I want to do quantum calculations really really bad!"

Of course, 3 mos her salary vs 3 mos my salary would have bought me about as much diamond quantum computing as I got at the time anyways. Se la vi.
