论文摘要
量子纠缠与经典不当行为之间的关系是在多模式挤压状态的背景下考虑的。在挤压状态的Bogoliubov转换中,用复杂的高斯随机变量代替运算符,我们发现所产生的转换变量不仅相关,而且不适当。考虑了光子检测的简单阈值超出模型,并用于证明不当的高斯随机变量的行为如何模仿纠缠光子对时,当进行序列后的巧合。
The relationship between quantum entanglement and classical impropriety is considered in the context of multi-modal squeezed states of light. Replacing operators with complex Gaussian random variables in the Bogoliubov transformations for squeezed states, we find that the resulting transformed variables are not only correlated but also improper. A simple threshold exceedance model of photon detection is considered and used to demonstrate how the behavior of improper Gaussian random variables can mimic that of entangled photon pairs when coincidence post-selection is performed.
