"Lockheed-Martin signs on for D-Wave prototype computer"
 30th May 2011
  http://www.theregister.co.uk/2011/05/30/dwave_lockheed_martin/

  "For example, while the company describes the machine as offering
   128 qubits of processing, other physicists say the D-Wave paper
   in Nature demonstrates only "non-classical effects" (ie,
   behaviours that appear to happen at a quantum scale) in an
   eight-qubit system."

  "According to MIT associate professor of computer science and
   electrical engineering Scott Aaronson, a long-time critic of the
   company, D-Wave's Nature article actually goes beyond its previous
   predilection for glossy-but-inaccurate media releases and shows off
   a quantum effect."
