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."
No, actually nitrogen impurities are the one thing keeping synthetic diamonds out of the jewelry market right now. Nitrogen turns diamonds a canary yellow, which can be considered desirable in fancy grades but is hardly desirable in the fiery rock category. Info here:

Women are like electronics: you don't know how damaged they are until you try to turn them on.

The whole notion isn't that different from doped silicon.
No folly is more costly than the folly of intolerant idealism. - Winston Churchill
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.

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?
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.
