Quantum calculations: maybe, maybe not

Regarding the quantum computer story I referenced a few days ago: oh well.

D-Wave Systems, the company that laid claim to the world's first functioning quantum machine now says it's not sure whether quantum computing is actually occurring. According to Wired, "all the evidence the company has indicates that the device is performing quantum computations, but [company chief executive Herb Martin] acknowledged there is some uncertainty."

Given the nature of quantum states that really tickles me.
