MOUNTAIN VIEW, Calif. - Quantum computing is such an elusive goal that even the company claiming to have the "world's first commercial quantum computer" acknowledged it isn't entirely sure the machine is performing true quantum calculations. ADVERTISEMENT

And independent quantum computing researchers said they are dubious of some of the claims made by D-Wave Systems Inc. because the privately held Canadian company has not yet submitted its findings for peer review, a standard step for gaining acceptance in scientific circles.

Many scientists believe that true quantum computing — which is based on the unusual properties of quantum physics — promises to solve certain factoring, simulation and other intensive problems faster than today's machines that rely on classical physics. Most say it's likely still years or decades away.

I like this quote:

He said all the evidence the company has indicates that the device is performing quantum computations, but he acknowledged there is some uncertainty.

I get it--the cutaway view shows the Central P(urring) Unit.

Cheers!
