The Birth of Spinplasmonics

CowboyNeal posted more than 6 years ago | from the making-heads-spin dept.

Education 34

Roland Piquepaille writes "You might have heard of spintronics, a technology that uses the magnetic quantum properties of the spin of electrons, or plasmonics, another one which 'involves the transfer of light electromagnetic energy into a tiny volume, thus creating intense electric fields.' Now, researchers at the University of Alberta (U of A) have merged these two nascent research fields to create a new nanotechnology field called spinplasmonics. According to the researchers, this new technology, which was already used to control the quantum state of an electron's spin to switch a beam of terahertz light, could one day be the basis for 'computers with extraordinary capacities.'"

Quantum Histrionics (1)

I'm thinking of inventing Quantum Histrionics. That's when everyone goes ga-ga over my latest quantum announcement, so that I can issue an IPO and walk away a millionaire -- over and over again.

"could one day be the basis for"

Of every 100 new technologies posted to the Slashdot homepage, it seems 99 could one day be the basis for vaporware.

Question about these Piquepaille submissions... (0, Offtopic)

chinodelosmuertos (805584) | more than 6 years ago | (#19363007)

OT but not really since it's about the fact that we get like 2 of these stupid Roland submissions a day. Do you notice how occasionally the link to the actual article, despite not going through Roland's page has one of those "=id_XXXX" identifiers at the end of the link? Does that mean that when we click on the link the article records that it is coming from a referral supplied from Roland, meaning that despite linking directly to the article, he is still getting credit for directing traffic that way? I'm new to this whole intarweb advertising scam nonsense, so can someone clue me in as to whether or not I'm crazy?

Re:Question about these Piquepaille submissions... (0)

Roland is a known spammer. He is not honest. I don't know why Slashdot continues to accept his stories despite the widespread condemnation of his behavior. People like him need to be shot. He steals other people's work and makes money off of it.

Just how extraordinary? (3, Funny)

mangu (126918) | more than 6 years ago | (#19363033)

'computers with extraordinary capacities.'

Computers today already have extraordinary capacities, at least compared to those of twenty years ago, which already had extraordinary capacities compared to those of forty years ago, and so on back to the first computer.

Let's have some numbers here, please. How much is that in Volkswagens or Libraries of Congress?

Re:Just how extraordinary? (0)

Anonymous Coward | more than 6 years ago | (#19363895)

Well, running Windows, the new supercomputers will be able to generate up to 20,000 BSODs per second, even without applying the parallel computing BSOD capabilities that Redmond has been known for.

Quite frankly, I am a programmer -- or was, while there was something to program; and I found the old Apple ][+ to be far more useful than the whiz-bangs of today (my PocketPC w/ PocketExcel excepted). And all that whiz-bang is simply used to drive better graphics, faster games, and more BSODs. I don't do games these days, and so I really could care less.

Give me a good programming language for my pocket PC, and and easy way to transfer from pocket-pc to pocket-pc via infrared, and I'll be happy and get quiet.

But i dont have a problem with roland. Everybody if fine to submit as much as he wants.

What i DO have a problem with is the fact that ./ editors dont give a fuck and continue so put is submission on the frontpage.

Yeah, we KNOW they are all idiots, corrupt and incompetend, by why not even try to hide it a bit?

Btw, is cowboyneal back from brokeback mountain yet?

The Law of Accelerating Returns (0)

Anonymous Coward | more than 6 years ago | (#19364199)

http://www.kurzweilai.net/articles/art0134.html?pr intable=1 [kurzweilai.net]

Surely you have all read this?

Moore's Law is just the beginning... we have accelerating returns because we shift paradigms when an individual technology falls flat in growth. This is an example of just one possible future paradigm that may continue or even accelerate our exponential growth.

What will we do with all this computer power?

Eventually someone will implement an Artificial General Intelligence (AGI [springer.com] ) system (either by evolving or otherwise brute-force production, human brain simulation/reverse-engineering/uploading, or by actually understanding intelligence and developing a novel theoretical architecture). This piece of intelligent software will be capable of doing the high-level, common sensical, intelligent thinking and work that a human can do, and the computational resources that are cognitively available to this intelligence will grow extremely fast with its revenue and the continued acceleration of hardware development (not to mention its massively accelerating software architecture and data stores and optimizations thereof)- e.g. it will be able to do more and more work, more intelligently, and more quickly, as time goes on. If the efforts of the intelligence are focused on researching and developing more powerful hardware and software, it can self-improve in ways completely unimaginable by human intelligences, sending the growth of technology into a feedback loop with the growth of intelligence.

When this AGI exceeds the intelligence of any human (who run about 10^16 neural ops/sec, have mortal and error prone bodies, zero growth in computational resources, no access to source code or underlying machinery, no end-user-modifiable software-code (if it were accessed), etc etc), which may happen very quickly [singinst.org] , it's called the Singularity [wikipedia.org] .

Physics may or may not have some upper limit on the ability of a given computational process to control the Universe to its *desired* ends, but this is a quick way to find out.

We need to be sure we have a *Friendly* AI (check out Singularity Insitute [singinst.org] )

Re:The Law of Accelerating Returns (1)

cluckshot (658931) | more than 6 years ago | (#19370129)

Never underestimate the power of human stupidity. As the computer singularity approaches the human stupidity that grows out of it accelerates. The resulting situation nullifies the singularity.

I suppose if we actually replicate the processes of the human brain in a chip or such we may begin to have artificial intelligence. At this time however; nothing we have even resembles this. The process we use to extract information from sensor data at this time has no capacity to develop information without being preloaded with it. The process grows in demand on the process geometrically as new items are added to the information list. (HINT HINT!!!!!) No danger exists as long as this reality continues of competition by computers to human "intelligence."

"According to the researchers, this new technology, which was already used to control the quantum state of an electron's spin to switch a beam of terahertz light, could one day be the basis for 'computers with extraordinary capacities." If you use an electron's spin to switch a beam of light (i.e. the light is in a state of
  • flux
), AND the light could equal extraordinary
  • capacity.
Then wouldn't that make this a "Flux Capacitor?"

Binary (0)

Anonymous Coward | more than 6 years ago | (#19364569)

the spin can either be a -1/2 or +1/2 . This is esentially the same as binary in our computers now... however, if we can have computers use molecular structures for the binary representations instead of magnets... this is what they are talking about.

I understand user tags are basically emasculated now -- tags no longer have any balls.

So, SCREW the system! Tag it 'ohnoitsroland' to show the eds how tired you are of Roland's drivel intended to whore out his pay-for-click blogs. And thank you.

Corrections to the press release (2)

plasmonicfocus (1041558) | more than 6 years ago | (#19365663)

This press release has a few misleading pieces that should be corrected for the public record:

"The spintronics field is barely a dozen years-old...The field of plasmonics, which is even younger than spintronics..."

This is patently untrue. Work on plasmon and surface plasmon physics has been going on for more than 50 years. It is certainly true that the name 'Plasmonics' is rather recent, and fabrication capabilities have advanced dramatically to better exploit these effects, but the field of study is fairly well established.

"One of the main challenges for plasmonics researchers is finding a way to propagate light over a long distance through solid materials."

Spintronics will not mitigate this problem. There are many plasmonic structures which have relatively long propagation lengths, but when one confines the field to lateral dimensions less than 1/100th of the wavelength, the propagation length is going to be very short, regardless of the electron spin.

light electromagnetic energy (1)

StrawberryFrog (67065) | more than 6 years ago | (#19366411)

" the transfer of light electromagnetic energy into a tiny volume, thus creating intense electric fields."

Would anyone care to translate into English, and for bonus points give us an idea of why we should care?
I mean, I didn't even know that electromagnetic radiation came in light and heavy varieties.

Re:light electromagnetic energy (0)

Anonymous Coward | more than 6 years ago | (#19367473)

Think light or dark, this means we are one step closer to optical computing. If you know anything about what is causing the limits of computational speed on current technology (clock speed limits due to heat generation, and electronic switching speeds), you'll see the promise of going optical could make computers capable of speed orders of magnitude faster.
