论文摘要
实验研究了包含大约25个光子对的双子梁的纠缠逐渐损失，并通过实验研究了外部噪声的增加。纠缠是通过非经典性深度和与几个非经典性标准相关的非经典性计数参数来量化的。分析的多模式双光束的强度力矩减少到单模一度的强度力矩可以确定否定性作为纠缠的另一个量词。并行分析了原始光封直方图和重建的光子数分布。
Gradual loss of the entanglement of a twin beam containing around 25 photon pairs with the increasing external noise is experimentally investigated. The entanglement is quantified by the non-classicality depths and the non-classicality counting parameters related to several non-classicality criteria. The reduction of intensity moments of the analyzed multi-mode twin beams to single-mode ones allows to determine the negativity as another quantifier of the entanglement. Both the raw photocount histograms and the reconstructed photon-number distributions are analyzed in parallel.
