Optical ising machine
WebIn parallel to the fast- growing exploratory efforts on quantum computing, we proposed and demonstrated that Ising machines can be implemented using a network of optical parametric oscillators, where the collective quantum-noise driven phase bifurcation in the network can be a computational resource for tackling these hard problems. WebMay 22, 2024 · Abstract We report a coherent Ising machine (CIM) that can simulate the Ising model with external magnetic fields. To represent Ising spins, the CIM employs degenerate optical parametric oscillator (DOPO) pulses, which are coupled by a measurement-feedback scheme.
