摘要: 伊辛机是一种基于伊辛模型解决组合优化问题的计算机器, 其中基于时分复用马赫-曾德尔调制器 (MZM)的相干伊辛机其光学部分较为简单, 但是反馈控制电路比较复杂。本文利用NI myRIO-1900模块, 实现了MZM伊辛机电路系统中AD、DA和FPGA等硬件的集成, 并用LabVIEW软件实现无线编程控制, 使得MZM伊辛机变得更加易于使用。对反铁磁方格模型的实验结果表明, 该伊辛机利用系统自身电路噪声可实现自旋分岔, 找到100个自旋的基态时间为1.25 s, 最高可找到1156个自旋的基态; 加入随机噪声后, 最高可实现2704个自旋的基态搜索。该伊辛机在解决实际组合优化问题方面具有潜在的应用价值。

Abstract: The Ising machine is a computing device designed to address combinatorial optimization problems based on the Ising model. Among them, the coherent Ising machine based on time-division multiplexing Mach-Zehnder modulator (MZM) has a relatively simple optical component, yet its feedback control circuit is intricate. In this work, NI myRIO-1900 module is used to realize the integration of the circuit system of MZM Ising machine, including the hardware system such as AD, DA, FPGA, etc., and LabVIEW software is used to realize the wireless programming and control, enhancing the usability of the MZM Ising machine. The experimental results of the antiferromagnetic square lattice model demonstrate that the Ising machine can achieve spin bifurcation through the utilization of the system's own circuit noise. It only takes 1.25 seconds to find the ground state for 100 spins, and can find the ground state for 1156 spins in this condition. After adding random noise, it can conduct searches for2704-spin ground state. This Ising machine has potential application value in solving practical combinatorial optimization problems.
