AnonTechie points us towards updates on the evaluation of D-Wave's annealing devices.

From Phys.org's reporting on the latest tests:

With cutting-edge technology, sometimes the first step scientists face is just making sure it actually works as intended. The USC Viterbi School of Engineering is home to the USC-Lockheed Martin Quantum Computing Center (QCC), a super-cooled, magnetically shielded facility specially built to house the first commercially available quantum computing processors; devices so advanced that there are only two in use outside the Canadian lab where they were built. The first one went to USC and Lockheed Martin, and the second to NASA and Google. Since USC's facility opened in October 2011, a key task for researchers has been to determine whether D-Wave processors operate as hoped using the special laws of quantum mechanics to offer potentially higher-speed processing, instead of operating in a classical, traditional way.

    they're no faster than a classical computer

    From what I've read earlier, Google and Lockheed don't really care about the speed of the 512-bit unit. They're looking to get experience using the technology so that when a 4K unit is available, they can re-run their existing code and solve problems faster than a room full of supercomputers.

    Don't get too excited. A single core of a mid-grade desktop processor can outperform D-Wave (one and two). Imagine what $10mil could buy you instead of a D-Wave and i think you can understand people's hesitation. I'm not saying it doesn't have promise or isn't quantum. I'm just saying that it is a HUGE waste of money for practical use. I can completely see academic use though where you can poke and prod the thing to get something non-classical out of it.
