论文摘要
我们比较了噪声相关性和连贯的ISING机器（CIMS）与光学延迟线，测量反馈和平均场耦合的成功概率。我们从理论上研究了这些CIM中的噪声相关性的三个指标：量子纠缠，量子不一致和规范坐标的归一化相关性。成功概率是通过基于Wigner分布函数的截短随机微分方程的数值模拟获得的。结果表明，成功概率与归一化的相关函数更直接相关，而不是纠缠或量子不一致。
We compared the noise correlation and the success probability of coherent Ising machines (CIMs) with optical delay-line, measurement feedback, and mean-field couplings. We theoretically studied three metrics for the noise correlations in these CIMs: quantum entanglement, quantum discord, and normalized correlation of canonical coordinates. The success probability was obtained through numerical simulations of truncated stochastic differential equations based on the Wigner distribution function. The results indicate that the success probability is more directly related to the normalized correlation function rather than entanglement or quantum discord.
