Entanglement and correlation of photons play a central role in quantum information and communication. There are two types of photon correlations: one usually exists in a two‐particle entangled state first conceived by Einstein, Podolsky, and Rosen (EPR) in 1935, while the other occurs in a thermal light source found by Hanbury Brown and Twiss (HBT) in 1956. Many studies are concerned with the physical nature and differences behind the two types of photon correlations. Here, a holography‐inspired linear optical system that generates a pair of conjugate chaotic beams is proposed, which include both HBT‐type and EPR‐like correlations. From principle to experimental generation, the study presents a classical paradigm of a simple bi‐correlation light source for diverse quantum‐mimic applications such as two‐photon imaging.

随机全息术：用热光子产生类似 EPR 的相关性


光子的纠缠和相关性在量子信息和通信中起着核心作用。光子相关性有两种类型：一种通常以双粒子纠缠态存在，由爱因斯坦、波多尔斯基和罗森 （EPR） 于 1935 年首次提出，而另一种则出现在 Hanbury Brown 和 Twiss （HBT） 于 1956 年发现的热光源中。许多研究关注两种光子相关性背后的物理性质和差异。在这里，提出了一种受全息启发的线性光学系统，该系统产生一对共轭混沌光束，其中包括 HBT 型和类似 EPR 的相关性。从原理到实验生成，该研究提出了一种简单的双相关光源的经典范例，用于各种量子模拟应用，例如双光子成像。
