Abstract

Over the last several decades, quantum entanglement has been intensively studied for potential applications in quantum information science. Although intensive studies have progressed for nonlocal correlation, fundamental understanding of entanglement itself is still limited. Here, the quantum feature of anticorrelation, the so-called HOM dip, based on probabilistic entangled photon pairs is analyzed for its fundamental physics and compared with a new method of on-demand entangled photon pair generations using coherent light. The fundamental physics why there is no correlation in HOM dip measurements is answered, and new coherence quantum physics is proposed for macroscopic quantum entanglement generations.
使用相干光子的按需量子相关控制
在过去的几十年里,量子纠缠在量子信息科学中的潜在应用得到了深入的研究。尽管对非局域相关的深入研究取得了进展,但对纠缠本身的基本理解仍然有限。本文分析了基于概率纠缠光子对的反相关量子特性(HOM dip)的基本物理性质,并与一种利用相干光按需生成纠缠光子对的新方法进行了比较。解答了为何HOM倾角测量没有相关性的基本物理问题,并提出了新的相干量子物理用于宏观量子纠缠世代。
