  • COHERENT ISING MACHINE WITH OPTICAL ERROR CORRECTION FOR OPTIMIZATION SOLUTION GENERATOR SYSTEM AND METHOD
    Publication number: 20240419958
    Abstract: A coherent Ising machine may comprise a pump pulse generator configured to generate optical signal pulses; an optical error correction circuit configured to generate optical error pulses; and a main ring cavity configured to store the optical signal pulses and the optical error pulses, wherein the optical error pulses cause the coherent Ising machine not to converge on a local minima of Ising solution and continue to explore nearby states.

  • EFFICIENT SAMPLING SYSTEM AND METHD OF GROUND-STATEAND LOW-ENERGY ISING SPIN CONFIGURATIONS WITH A COHERENT ISSING MACHING
    Publication number: 20240185111
    Abstract: A system and method for efficient sampling of ground-state and low-energy Ising configurations. The system may be implemented using the nonlinear stochastic dynamics of a measurement-feedback-based coherent Ising machine (MFB-CIM). A discrete-time Gaussian-state model of the MFB-CIM may capture the nonlinear dynamics. The system and method requires many fewer roundtrips to sample than for other known systems.
