technology.guardian.co.uk — A Canadian company with substantial venture capital backing claims to have built a "quantum computer" that will ultimately solve problems beyond the power of conventional systems - and will demonstrate it over a live link next week.

I'll never forgive the gay community for co-opting the rainbow. I used to love looking at and thinking about rainbows but now everytime I think about one the mental image of some guy giving another guy a rimjob rudely intrudes into my consciousness.

This place is filled with morons. Did that guy just refer to Canada as "canadia" ? Unbelievable.

Heh.. I'm surprised it wasn't built at Waterloo

Actually, it is not known whether or not NP-Complete problems are efficiently computable in the quantum model. It may seem natural to assume that since qubits give you all of this parallelism (i.e. superposition) that NP "search style" problems are good to go, but extracting a solution seems difficult. If anything, the current literature seems to point in the negative direction.That is not to say that there are problems that are assumed hard (but not provably so) in the classical model, e.g. factoring and discrete log, that are efficiently resolved in the quantum model, so one could issue challenges with these kinds of problems. That being said, this seems like a hoax at best. The idea of a "quantum computer" as we know computers today is just laughable with the state of knowledge in this area today.

Virtually no invention belongs purely in one country. Also, by population, there oughta be roughly 10x as many "American" inventions as "Canadian" ones, but it's purely subjective. Is an invention if its inventor was born in Canada? Raised in Canada? Came up with the idea in Canada? R&D'd the idea in Canada? Loved Canada? It's hugely debatable, to be sure. But to dismiss Canadian contribution to modern technology would be a travesty, to say the least. America did not create every bit of technology known to humankind, you know.
