There have been years of controversy about whether the superconducting quantum annealing computers manufactured by D-Wave are a) quantum computers; and b) fast enough for a) to matter. Now a test of the 512-qubit Vesuvius chip establishes at least that computing based on quantum annealing is, in the words of a computer science professor at Amherst College, "in some cases, really, really fast."
