D-Wave Systems Inc. finally sells 512-qubit quantum computers
See "Daniel Lidar talking about experiments on the D-Wave One at USC," at D-Wave's "Hack the Multiverse" blog. Apparently, I can not leave a link, but one minute into the presentation, it reveals that Lockheed Martin purchased a D-Wave 2, "Vesuvius" processor, but it is still being calibrated and is not yet operational. Numerous others must have purchased the system, including the NSA. Also check out the brief video, "Lockheed Martin piece about D-Wave technology."
