Quantum annealing combines the neolithic technology of slow thermal cooling with quantum mechanical tunneling, to bring a physical system faster towards its ground state. The Canadian company D-Wave systems has recently built and sold programmable quantum annealing devices using this effect to find solutions to hard optimization problems. I will present results of experiments designed to answer the crucial questions about these controversial devices: are they quantum or classical? And are they faster than classical devices?
