摘要

光的二阶相干性是一个公认的物理量，用于评估光的量子特性，其特性已在量子光学领域得到广泛研究。最近，有人提出可以利用二阶相干性作为量子纠缠的指标。在本研究中，我们评估了移动镜像模型背景下的二阶相干性，该模型是黑洞霍金辐射的模拟模型。我们讨论了纠缠与霍金辐射的二阶相干性之间的关系，并关注了霍金辐射的热效应导致的 "噪声 "效应，这种效应降低了双量子比特探测器纠缠捕获协议中的量子相关性。

Second-order coherence as an indicator of quantum entanglement of Hawking radiation in moving-mirror models

The second-order coherence of light is a widely recognized physical quantity used to assess the quantum characteristics of light, and its properties have been extensively investigated in the field of quantum optics. Recently, it has been proposed that second-order coherence can be utilized as an indicator of quantum entanglement. In this study, we evaluated the second-order coherence in the context of the moving-mirror model, which serves as an analog model for Hawking radiation from a black hole. We discuss the relation between entanglement and the second-order coherence of Hawking radiation paying attention to the “noise” effect due to the thermality of Hawking radiation, which reduces the quantum correlation in the entanglement-harvesting protocol with two-qubit detectors.
