“Using a specific test problem involving eight qubits, we have verified that the D-Wave processor performs optimization calculations [that is, finds lowest-energy solutions] using a procedure that is consistent with quantum annealing and is inconsistent with the predictions of classical annealing,” said Daniel Lidar, scientific director of the Quantum Computing Center and one of the researchers on the team.
“Our work seems to show that, from a purely physical point of view, quantum effects play a functional role in information processing in the D-Wave processor,” said Sergio Boixo, first author of the research paper, who conducted the research while he was a computer scientist at ISI and research assistant professor at USC Viterbi.
