Hardware, Embedded Systems "But a powerful new type of computer that is about to be commercially deployed by a major American military contractor is taking computing into the strange, subatomic realm of quantum mechanics. In that infinitesimal neighborhood, common sense logic no longer seems to apply. A one can be a one, or it can be a one and a zero and everything in between - all at the same time. [...] Now, Lockheed Martin - which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago - is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business." I always get a bit skeptical whenever I hear the words 'quantum computing', but according to NewScientist, this is pretty legit.

Even more important can it be used to make certain encryption algorithms useless.

That is the thing I always care about.

And it is always the government agencies or government contractors that gets these kinds of systems first.

From an other article linked in the comments:

"There was a further limitation. Theoretically, the quantum computer should operate at a temperature of 0 kelvin, but such extreme cooling is impossible in practice, so D-Wave repeatedly ran the system at slightly above zero in the hope of reaching the lowest-energy state. Due to these higher temperatures the calculation got the right answer only 13 times after 10,000 attempts."

So eventually you might end up with something like a couple of thousand guesses to decrypt certain data.

If that is true, that could be bad.
