[freenet-chat] Possible progress on quantum computing

[Matthew Toseland]

The article states that adiabatic quantum computers cannot be used to
solve crypto, so presumably they have a limited range of operations? It
sounds very odd. The researcher on page 2 said he didn't think it was
very likely that they can scale it up to 1000 qbits... we'll see.

Unless D-Wave are total frauds or their science is all wrong, the shit
is about to hit the fan for computer security.

Rose says D-Wave plans to submit its results for peer review at a major
journal. He notes that experts will be given a chance to inspect the
system, and that the company plans to make its prototype available
online free of charge to stir interest. Users would enter a problem to
be solved, and the device would send the solution from Canada.

And how exactly would users know that it was the quantum computer rather
than a human or ordinary computer answering their queries? "There's
really no way to convince a skeptic who's accessing the machine
remotely," Rose admits. For now, D-Wave's device is slower than an
inexpensive home computer, but Rose says a potentially faster
1,000-qubit version should be available by the end of next year.
