多模波导中横模对Bell不等式破坏的数值模拟

Numerical simulation of Bell inequality's violation using optical transverse modes in multimode waveguides

Jian Fu, Xun Zhang

摘要:

数值计算证明了基于多模波导中经典光场横模的“模纠缠态”违反了贝尔不等式。通过数值模拟Bell不等式的相关测量方案,得到了两个纠缠经典场强度涨落的归一化关联函数.利用关联函数,得到了Bell不等式的最大违反.这意味着两个经典场的模式纠缠态,虽然空间上分离,提出了一个非局域相关。

英文摘要:

We numerically demonstrate that "mode-entangled states" based on the transverse modes of classical optical fields in multimode waveguides violate Bell's inequality. Numerically simulating the correlation measurement scheme of Bell's inequality, we obtain the normalized correlation functions of the intensity fluctuations for the two entangled classical fields. By using the correlation functions, the maximum violations of Bell's inequality are obtained. This implies that the two classical fields in the mode-entangled states, although spatially separated, present a nonlocal correlation.
