As promised, here's a photo from my holiday of something other than flowers. I don't know exactly what it is, but assume it is a kingfisher of some description. (Kookaburra shape and size, but colouring is different.)
It seems that bubbles of electrons lined up in ultracold liquid helium could be used to build a quantum computer capable of carrying out a staggering 1030 simultaneous calculations."
Actually, as the article ends with this:
Because each qubit carries two values, a quantum computer with two qubits could carry out four parallel calculations, one with three qubits eight calculations, and so on. "I see no major technical obstacles to the system I envisage working with 100 qubits," says Yao. "That means it could do 1000 billion billion billion operations all at once."
the reference to "1030" presumably is meant to be "10 to the power of 30" (10 followed by 30 zeros).
Has anyone worked out how you would use that computing power in practice?
The US Iraq survey team, sent in after the war, failed to find any WMD after one of the most intensive hunts in history. Sir Christopher suggests they could have been "spirited out of the country into Syria or maybe even Iran. That is a possibility". To the Americans, though, Sir Christopher says, the war was always about regime change, not WMD. "One of the things that came to me when writing was how political the war was. This wasn't just a war, it was a political war." The US, he says, wanted to "replace a bad government with a good government". It was, he says, the "neo-con vision".
US officials who planned the war, such as deputy defence secretary Paul Wolfowitz, "thought it was possible to bring not perfect democracy but start with a fairly rough and ready version that would be the basis from which you could move on to higher things".
"Put it like that and it doesn't sound so loony," he says.
And despite the current situation in Iraq, Sir Christopher remains an admirer of Mr Bush. "I have got to declare an interest: I like George W Bush. In public, on the whole, he doesn't do himself justice, at least for a European audience. In private, from the very first time I met him, I found him articulate and interesting. He did do detail. You can argue, millions will, that what he did with those details and the policies he created out of them are not to our liking. But the portrait of an ideological, religious simpleton is wildly off-beam."
