Two weeks ago, the Canadian company D-Wave Systems announced the first commercially available quantum computer, the D-Wave One. They claim that it operates on 128 qubits.

Before you panic: most scientists are 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 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. 😉
