"Tapping Quantum Effects for Software that Learns
 Defense contractor Lockheed Martin paid $10 million for
 a "quantum computer" that is also being tested by Google."

斜め読みしたら、副題にもある通り：
  "Google has been experimenting with D-Wave's technology for several
   years as a way to speed up software that can interpret photos.
   The company's software engineers use it as a kind of cloud service,
   accessing a system at D-Wave's Vancouver headquarters over the
   Internet. In 2009, the company published papers showing that using
   the quantum system outperformed conventional software running in
   a Google data center."

"Machine Learning with Quantum Algorithms"

最後に
  "Today, at the Neural Information Processing Systems conference
   (NIPS 2009), we show the progress we have made. We demonstrate
   a detector that has learned to spot cars by looking at example
   pictures. It was trained with adiabatic quantum optimization using
   a D-Wave C4 Chimera chip. There are still many open questions but
   in our experiments we observed that this detector performs better
   than those we had trained using classical solvers running on the
   computers we have in our data centers today. Besides progress in
   engineering synthetic intelligence we hope that improved mastery of
   quantum computing will also increase our appreciation for the
   structure of reality as described by the laws of quantum physics."

※NIPSは Neural Networksの学習理論等に関して、最難関の国際会議です。
少なくとも私が大学院生時代は、多分今でもそのはず。

※Googleは NIPSに熱心なようで
