论文摘要
我们从理论上研究了洪曼干预实验中的不可区分性和量子纠缠之间的关系,并将这些量子机械原理与纠缠一夫一妻制定理联系起来。采用量子相干性理论,我们计算了频率纠缠光子的主管的检测统计数据,并在重合检测概率中找到了一个新的附加术语,该概率与有限的带网效应产生的光谱无关的光谱相关,因此与低频分离相关,因此与低频分离或大型单球相关。与以前的工作相比,我们在平等基础上处理所有光子自由度(DOF)。
We investigate the relation between indistinguishability and quantum entanglement in Hong- Ou-Mandel-interference experiments theoretically and relate these quantum mechanical principles to the theorem of entanglement monogamy. Employing Glaubers theory of quantum coherence we compute the detection statistics in HOM-interference of frequency entangled photons, and find a new additional term in the coincidence detection probability, which is related to the spectral indistinguishability of the considered photons that arises from finite bandwidth effects, and therefore is relevant in the limit of low frequency separations or large single-photon bandwidths. Compared to previous work in that context we treat all photonic degrees of freedom (DOF) on equal footing.
