Scientists dubious of quantum computer claims
"MOUNTAIN VIEW, California (AP) -- 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.
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.
D-Wave held its first public demonstration Tuesday of a machine it claims uses quantum mechanics to solve a certain type of problems, such as searching a database for matching molecular structures.
But the company did not make the machine available for inspection and instead showed video from a remote location, saying it was too sensitive to be easily transported."
