论文摘要
在过去的几十年中，通过自发参数降低转换过程从\ c {hi}^（（2））非线性光学材料产生的纠缠光子对已被深入研究，以实现各种量子相关性，例如贝尔不等式违规和反相关。在Mach-Zhhnder干涉仪中，还研究了光子DE Broglie波长，以通过克服标准量子极限的增强相位分辨率进行量子传感。在这里，在微观方案中的双分部分纠缠光子对，还针对宏观连贯性纠缠的产生，对量子性的基本原理进行了可控的量子相关性研究。
Over the last several decades, entangled photon pairs generated from \c{hi}^((2)) nonlinear optical materials via spontaneous parametric down conversion processes have been intensively studied for various quantum correlations such as Bell inequality violation and anticorrelation. In a Mach-Zehnder interferometer, the photonic de Broglie wavelength has also been studied for quantum sensing with an enhanced phase resolution overcoming the standard quantum limit. Here, the fundamental principles of quantumness are investigated in an interferometric scheme for controllable quantum correlation not only for bipartite entangled photon pairs in a microscopic regime, but also for macroscopic coherence entanglement generation.
