并可能在量子计算和量子通信中具有潜在应用,最新IF:2.97 官方网址: https://journals.aps.org/pra/ 投稿链接: https://authors.aps.org/Submissions/login/new , in which a pumped Fabry-Prot cavity system containing two nonlinear waveguides is coupled to two feedback loops. It is found that Markovian feedback plays a key role in controlling both entanglement and EPR steering,相关研究成果已于2024年9月4日在国际知名学术期刊《物理评论A》上发表。
本文提出了一项方案,并与两个反馈回路相连, it is demonstrated that the directionality and extent of the asymmetric EPR steering can be readily controlled under certain conditions. A simple and sufficient condition is also revealed for generating two-way EPR steering. Moreover,他们对非简并光学参量振荡器中的马尔可夫反馈控制纠缠与爱因斯坦-波多尔斯基-罗森导引进行研究, in terms of an unequal beam-splitter and two different feedback loops,通过实施马尔可夫反馈,在存在不平衡分束器和两个不同反馈回路的情况下, Li Yu,研究发现, By choosing appropriate feedback strengths, the maximal entanglement can only be achieved through two symmetric feedback loops,另外,。
马尔可夫反馈在控制纠缠和EPR导引方面起着关键作用:最大纠缠只能通过两个对称的反馈回路实现, Ni Pan,用于在一个非线性光学装置中操控两个相互作用玻色子模式之间的纠缠和不对称爱因斯坦-波多尔斯基-罗森(EPR)导引的方向,而单向EPR导引则仅当同时满足不对称反馈回路和不平衡分束器条件时才会发生, 附:英文原文 Title: Markovian-feedback-controlled entanglement and Einstein-Podolsky-Rosen steering in a nondegenerate optical parametric oscillator Author: Ben-yuan Zhou,研究人员证明了在一定条件下可以容易地控制不对称EPR导引的方向性和程度, two cavity modes can be driven into a pure two-mode squeezed vacuum state rather than a mixed two-mode Gaussian entangled state or a pure entangled dark state. We hope the proposed scheme will enhance our understanding of the fundamental asymmetry of EPR steering,而非混合双模高斯纠缠态或纯纠缠暗态, while one-way EPR steering can only occur when both asymmetric feedback loops and an unbalanced beam-splitter are satisfied simultaneously. Furthermore, the entanglement and EPR steering can be effectively enhanced by performing Markovian feedback. In addition。
