Title:
イジングモデルの計算装置
Document Type and Number:
Japanese Patent JP6697420
Kind Code:
B2
Abstract:
To provide a calculation device of an Ising model which is constructed without using a PSA which is a special mechanism.SOLUTION: A calculation device of an Ising model comprises: a ring resonator 1 which repeatedly transmits plural light pulses corresponding to plural spins of the Ising model in a pseudo state, and having a same frequency; an external light pulse input part 5; a light pulse measurement part 35; and a calculation device 4. The external light pulse input part 5 modulates phases and amplitudes of plural light pulses which are overlapped to plural light pulses in the resonator 1 based on a mutual action calculated by the calculation device 4, for implementing a mutual action related to a certain light pulse. The light pulse measurement part 35 converts phases of the plural light pulses which are measured until becoming in a stable state, into spins of the Ising model, in a step in which, a feedback loop control formed of the light pulse measurement part 35, the calculation device 4, the external light pulse input part 5 is repeated, for acquiring a value of a spin of the Ising model.SELECTED DRAWING: Figure 2
