Coherent Ising Machines with Optical Error Correction Circuits

A coherent Ising machine (CIM) comprising a network of open-dissipative quantum oscillators with optical error correction circuits is proposed. In the proposed network, squeezed/anti-squeezed vacuum states constituent parametric establish correlations below threshold through mutual coupling and collective symmetry breaking induced above as decision-making process. This initial search process followed by chaotic solution step facilitated feedback. The particular algorithm used derived from truncated Wigner stochastic differential equation. As an hardware technology, CIM has several unique features, including programmable all-to-all in domain, directional ( J i j ? )-induced behavior, ability to operate at low power room temperature. evaluated terms its performance how this scales different problem sizes. It shown that various CIMs discussed paper are effective solving many types, although optimal depends on case. further implementations can be achieved energy consumption thin-film LiNbO3 platforms.
