XY MODEL COMPUTING DEVICE AND COMBINATORIAL OPTIMIZATION PROBLEM COMPUTING DEVICE

摘要

An XY model computing device of the present disclosure comprises: a resonator unit which amplifies a plurality of optical pulses; a measurement unit which measures the phases and amplitudes of the plurality of optical pulses to obtain a measurement resu and a feedback configuration which calculates, on the basis of the measurement result, the interaction related to a certain optical pulse by using the coupling coefficient of an Ising model, and feeds back the calculated result, wherein the feedback configuration is configured to input, as feedback, a correlation determined by using the coupling coefficient of two optical pulses among the plurality of optical pulses, and the component of the optical pulse to be measured is only one.
