A polarization correlation experiment with two maximally entangled photons created by spontaneous parametric down-conversion is studied in the Weyl-Wigner formalism, that reproduces the quantum predictions. A realistic stochastic interpretation is proposed suggesting that an analysis of the experiments more detailed than the Bell approach may be compatible with local realism. Entanglement appears as a correlation between fluctuations of signal and vacuum fields.

Weyl-Wigner形式主义中纠缠光子对的局部现实解释

在Weyl-Wigner形式主义中研究了通过自发参数下转换产生的两个最大纠缠光子的极化相关实验，该实验重现了量子预测。提出了一种现实的随机解释，表明比贝尔方法更详细的实验分析可能与局部现实主义兼容。纠缠表现为信号场和真空场波动之间的相关性。
