USC finds that D-Wave's quantum computer is real, maybe

D-Wave has had little trouble lining up customers for its quantum computer, but questions have persisted as to whether or not the machine is performing quantum math in the first place. University of Southern California researchers have tested Lockheed Martin's unit to help settle that debate, and they believe that D-Wave's computer could be the real deal -- or rather, that it isn't obviously cheating. They've shown that the system isn't based on simulated annealing, which relies on traditional p...
