Diamonds Key To Quantum Computing
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."
So now diamonds are a supercomputer's best friend?
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.

The only value in natural diamonds over man made diamonds is "i have something you can't afford" [snob value]
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.
Where are we going and why are we in a handbasket?
I just can't see spending the rest of my life with someone who is that susceptible to advertising. Even if she's physically attractive, that much dumb strikes me as being a worse kind of ugly.
