相干Ising机中的噪声相关和成功概率

Noise correlation and success probability in coherent Ising machines

Yoshitaka Inui, Yoshihisa Yamamoto

摘要:

我们比较了相干伊辛机(CIM)与光延迟线,测量反馈,和平均场耦合的噪声相关性和成功概率。我们从理论上研究了这些耦合模型中噪声关联的三个度量:量子纠缠、量子不和谐和正则坐标的归一化关联。通过对基于Wigner分布函数的截断随机微分方程进行数值模拟,得到了成功概率。结果表明,成功概率与归一化关联函数有更直接的关系,而不是与纠缠或量子不协调有关。

英文摘要:

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.
