Abstract:

With the rapid development of artificial intelligence, many industries require massive computational power as technical support. Low-energy optical computing and quantum computing have emerged as the most promising solution for high-speed and large-scale data processing in the future. The optical parametric oscillations pulses are used as the computational bits in coherent Ising computing. A coherent Ising machine based on optical parametric oscillation can search for spin configurations at the ground state of the Ising model, thereby improving the computational speed and accuracy in solving combinatorial optimization problems. The improved coherent Ising machine can overcome the limitations of local minima, and its test results on large-scale combinatorial optimization problems have surpassed some classical algorithms, providing a new direction for solving various combinatorial optimization problems.

Key words: coherent Ising machine, optical parametric oscillator, combinatorial optimization problem
