Classical Signatures of Quantum Annealing
Dr. Graeme Smith
IBM TJ Watson Research Center
A Canadian company called D-Wave has recently made strong claims about the performance of their system, built without satisfying the usual requirements for quantum computation. Here we focus on showing that the evidence of quantumness given in the literature is extremely weak and is consistent with an effective classical description. Indeed, we find a classical model that is better correlated with the data from D-wave than their quantum model. We further show by comparing to the performance of classical simulated annealing that the idea that their current machines outperform classical computers is unfounded.
