Title:
イジングモデルの量子計算装置及びイジングモデルの量子計算方法
Document Type and Number:
Japanese Patent JP5354233
Kind Code:
B2
Abstract:
This computation device and method exponentially shortens a computation time of an NP-complete problem or the like mapped into an Ising model by exponentially shortening a computation time of the Ising mode. For each pair of a plurality of slave lasers, by controlling the intensity, the polarization, and the phase of light exchanged between two slave lasers using an attenuator and a wave plate, the magnitude and the sign of pseudo Ising interaction between two slave lasers are implemented. Then, after the plurality of slave lasers arrive at a steady state, by measuring the polarization of light generated by each slave laser with left-handed circular polarization and right-handed circular polarization used as bases, a pseudo spin of each slave laser is measured.
