论文摘要
在上个世纪,非本地量子相关一直是量子力学的主要问题。 Hong-ou-mandel(HOM)效应与光束分离器上的两光强度相关性有关,从而导致非经典光子束束现象。 HOM效应已用于通过Bell测量值来验证量子特征,例如量子中继器和光子学量子计算等量子技术。在这里,提出并分析了HOM效应的连贯版本,以了解反相关和纠缠的基本物理。为此,使用衰减激光器的同步调节剂对频率相关的相干光子对制备。对于HOM效应,频率相关光子之间的相位关系起着至关重要的作用。对于产品基础随机性,对称调制两个独立的MZI是不连贯的。在选择性宏观测量方案中,还讨论了两个独立光电探测器之间的经典强度产物。
Nonlocal quantum correlation has been the main issue of quantum mechanics over the last century. The Hong-Ou-Mandel (HOM) effect relates to the two-photon intensity correlation on a beam splitter, resulting in a nonclassical photon-bunching phenomenon. The HOM effect has been used to verify the quantum feature via Bell measurements for quantum technologies such as quantum repeaters and photonics quantum computing. Here, a coherence version of the HOM effect is proposed and analyzed to understand the fundamental physics of the anticorrelation and entanglement. For this, frequency-correlated coherent photon pairs are prepared in an independent set of Mach-Zhender interferometers (MZI) using a synchronized pair of modulators from an attenuated laser. For the HOM effect, the phase relation between frequency-correlated photons plays an essential role. For the product-basis randomness, the symmetrically modulated two independent MZIs are combined together incoherently. A classical intensity product between two independent photodetectors is also discussed for the same HOM effect in a selective macroscopic measurement scheme.
