Two weeks ago, the Canadian company [D-Wave Systems](http://www.dwavesys.com/ "D-Wave Systems") announced the first commercially available quantum computer, the D-Wave One. They claim that it operates on [128 qubits](http://en.wikipedia.org/wiki/Qubit "qubits"). Before you [panic](complexity.html "panic"): most scientists are [skeptical](http://en.wikipedia.org/wiki/D-Wave_Systems#Criticism "skeptical") about the claims of D-Wave Systems in general, and the actual 'quantum nature' of the D-Wave processor in particular. On the other hand, [Lockheed-Martin](http://www.lockheedmartin.com/ "Lockheed-Martin") apparently signed a multi-year contract with D-Wave Systems, and the purported price just for the D-Wave One is $10,000,000. So perhaps we should worry after all … who knows how many systems they delivered to the NSA or related agencies. 😉
