Diamonds Key To Quantum Computing 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."

    How nice now... The first quantum computer on the market will have to use diamonds.... So what will that mean? A $8 million price tag?

    So now diamonds are a supercomputer's best friend?
  • "Quantum diamonds are forever. Or are they?" --Lord Nimula

  • Diamond computers.
    Who cares if they work? People will buy them anyway.
  • From Wikipedia []: "LifeGem is the world's first company offering to synthesize diamonds from the carbonized remains of people or pets."

    Just another possibility for useful recycling.

      Maybe too obscure, foobsr. Only us old farts remember what a PET [] is. Kids these days...

    Maybe they should try with dilithium crystals.
  • Ok, you go get all the high tech expedition stuff, and I'll teach the gorilla sign language, then lets go get em!

    But do NOT pack any damned shaped charges!
    • 2nded and the first thing I thought when I saw this. Does this mean MC is right about other things???
  • We need to figure out how to make our control crystals less susceptible to Zat'n'ktel fire and resistant to staff blasts before production.

    Oh, and we might need to consider locking the compartments that hold our control crystals...
  • When diamonds are a nerds best friend.
  • is in my laptop? They could also make these artificially, putting in the precise concentration and distribution of nitrogen. All I heard was 'Quantum Computer' and 'persists for a real amount of time' and 'room temperature.'

    Science should be done with free, open sharing of the results, so that anyone, anywhere, can read the details and possibly come up with the next idea.

    These subscription journals are holding back science.

    The service of organizing peer-review is logically independent
    of whether something is in a limited distribution paid, paper
    journal. Sell google ads on the things if you must, dammit.

    I know its a bit offtopic but it pisses me off royally.

    Science is above all else about building shared knowledge.
    Period. If you're putting your findings behind firewalls,
    you are harming science.
    • 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

      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 i

      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?
    • Well yeah, we'd all like stuff to be free. Why should science be treated so specially in this regard?
    • rock on!

    • looking forward to quantum computing. This way, my system files on Windows will both have a rootkit and not have a rootkit at the same time!

      Yeah, but you won't know which until you check...
    • As with all things Quantum, its a model of what could be known.
      My Mum has already achieved what you're after

      Mom "but it didn't have a virus before you looked at it!"
      I "did it take 30 mins to boot?"

  • Can someone please tag this as "Zardoz" []?


  • Could you please build my quantum computer with cubic zirconia instead? I'm kinda on a tight budget. :-/
  • ...and the era of Glam Computing begins.
  • 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 dev

  • 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.
