Title:
QUANTUM COMPUTING DEVICE FOR ISING MODEL, QUANTUM PARALLEL COMPUTING DEVICE FOR ISING MODEL, AND QUANTUM COMPUTING METHOD FOR ISING MODEL
Document Type and Number:
WIPO Patent Application WO/2015/156126
Kind Code:
A1
Abstract:
In the present invention, a parametric oscillator (1) oscillates a plurality of pseudo spin pulses (SPi) having an identical oscillation frequency using parametric oscillation. An interactive implementation unit (5) carries out feedback implementation for the size and sign of interactions (proportionality coefficient λi + ΣJijσj + ΣKijkσjσk for σi) related to each pseudo spin pulse (SPi) using provisional measurement results for the oscillation phases φi (provisional) of the plurality of pseudo spin pulses (SPi). A pseudo spin measurement unit (6) measures the pseudo spin σi of the plurality of pseudo spin pulses (SPi) on the basis of final measurement results for the oscillation phases φi (steady) of the plurality of pseudo spin pulses (SPi).
