基于myRIO-1900实现2704个自旋的伊辛机
Implementation of a 2704-spin Ising machine based on myRIO-1900
摘要
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 for 2704-spin ground state.This Ising machine has potential application value in solving practical combinatorial optimization problems.关键词
