Claim Text:
1. An Ising model quantum computation device comprising: a plurality of coherent oscillators that have an oscillation mode in which light having left-handed circular polarization or right-handed circular polarization is generated; inter-oscillator optical path units that are arranged between two coherent oscillators for each pair of the plurality of coherent oscillators; inter-oscillator intensity control units that, for each pair of the plurality of coherent oscillators, are arranged in the inter-oscillator optical path units and implement a magnitude of pseudo Ising interaction between two coherent oscillators by controlling an intensity of light exchanged between the two coherent oscillators; inter-oscillator polarization control units that, for each pair of the plurality of coherent oscillators, are arranged in the inter-oscillator optical path units and implement a sign of the pseudo Ising interaction between two coherent oscillators by controlling polarization and a phase of light exchanged between the two coherent oscillators; and a polarization measuring unit that measures pseudo spins of the plurality of coherent oscillators by measuring polarization of light generated by the plurality of coherent oscillators with left-handed circular polarization and right-handed circular polarization used as bases after the plurality of coherent oscillator arrive at a steady state.
