Title:
SPIN-MODEL OPTICAL SAMPLING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2017/221390
Kind Code:
A1
Abstract:
The present disclosure is a spin-model optical sampling device Q1 characterized by being provided with: a laser oscillation control unit 1 for controlling the oscillation of a plurality of lasers L that have the same oscillation frequency and are artificially made to correspond to a plurality of spins having phases having continuous values; an interaction implementation unit 2 for artificially implementing the phase and amplitude of the mutual interaction between the plurality of spins by controlling the amplitude and phase of mutual injection between a plurality of lasers L; a temperature implementation unit 2 for artificially implementing the temperatures of a plurality of spin systems by controlling the ratio between the amplitude of mutual injection between the plurality of lasers L and the noise amplitudes of the plurality of lasers L; and a sampling unit 3 for artificially measuring the phases of the plurality of spins at the ground state or an excited state of the plurality of spin systems by measuring the phases of the plurality of lasers L after the interaction and temperature of the plurality of spin systems have been artificially implemented and the plurality of lasers L have reached a steady state.
