Web[2, 3] Another example is the coherent Ising machine (CIM), which exploits the quantum-to-classical transition of mixed-state density operators in a quantum oscillator network. [ 4 - 7 ] Performance comparisons between QA devices and CIMs for various Ising models incorporating complete, dense, or sparse graphs have been reported. [ 8 ] WebJul 22, 2024 · Abstract Statistical spin dynamics plays a key role in understanding the working principle for novel optical Ising machines. Here, we propose the gauge transformation for a spatial photonic Ising machine, where a single spatial phase modulator simultaneously encodes spin configurations and programs interaction strengths.
