摘要

In the present invention, a parametric oscillator 1 oscillates a plurality of pseudo spin pulses SPi having mutually an identical oscillation frequency by using parametric oscillation, an interaction implementing unit 5 performs feedback implementation of a magnitude and a sign of interaction related to each pseudo spin pulse SPi (the proportionality coefficient λ_i+ΣJ_ijσ_j+ΣK_ijkσ_jσ_k with respect to σ_i) by using a tentative measurement result of oscillation phases ϕ_i (tentative) of the plurality of pseudo spin pulses SPi, and a pseudo spin measuring unit 6 measures the pseudo spins σ_i of the plurality of pseudo spin pulses SPi, based on a final measurement result of oscillation phases ϕ_i (steady) of the plurality of pseudo spin pulses SPi.
