论文摘要
基于模拟系统的ISING机器具有加速解决无处不在的组合优化问题的潜力。尽管有一些人工旋转以支持大规模的伊辛机器，例如量子退火器中的超导量子台和相干伊辛机器中的短光脉冲，由于超低等效温度或光相灵敏度，自旋连贯性是脆弱的。在本文中，我们建议使用从光电子参数振荡器产生的短微波脉冲作为旋转，以在室温下实现大规模且高相干性的ISING机器。提出的机器支持10,000次旋转，高相干导致准确的计算。此外，ISING机器与高速电子设备高度兼容，可提供可编程性，铺平了低成本，准确且易于实现的方式，以解决现实世界中的优化问题。
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.
