Abstract

Ising machines based on analog systems have the potential of acceleration in solving ubiquitous combinatorial optimization problems. Although some artificial spins to support large-scale Ising machine is reported, e.g. superconducting qubits in quantum annealers and short optical pulses in coherent Ising machines, the spin coherence is fragile due to the ultra-low equivalent temperature or optical phase sensitivity. In this paper, we propose to use short microwave pulses generated from an optoelectronic parametric oscillator as the spins to implement the Ising machine with large scale and also high coherence under room temperature. The proposed machine supports 10,000 spins, and the high coherence leads to accurate computation. Moreover, the Ising machine is highly compatible with high-speed electronic devices for programmability, paving a low-cost, accurate, and easy-to-implement way toward to solve real-world optimization problems.
微波光子成像机
基于模拟系统的伊辛机器在解决泛在组合优化问题方面具有加速的潜力。虽然已经报道了一些支持大型Ising机器的人工自旋,例如量子退火中的超导量子比特和相干Ising机器中的短光脉冲,但由于超低的等效温度或光学相位灵敏度,自旋相干性是脆弱的。本文提出利用光电参量振荡器产生的微波短脉冲作为自旋,实现室温下大规模高相干的伊辛机。该机器支持10,000个自旋,并且高相干性导致精确的计算。此外,伊辛机器在可编程性方面与高速电子设备高度兼容,为解决现实世界的优化问题铺平了低成本、精确和易于实现的道路。
