the entanglement and EPR steering can be effectively enhanced by performing Markovian feedback. In addition,imToken下载,两个腔模式可以被驱动进入纯双模压缩真空态。
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,另外, Li Yu, 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,研究人员还揭示了一个产生双向EPR导引的简单且充分的条件。
研究发现, Gao-xiang Li IssueVolume: 2024/09/04 Abstract: We propose a scheme to manipulate entanglement and the direction of asymmetric Einstein-Podolsky-Rosen (EPR) steering between two interacting bosonic modes in a nonlinear optical apparatus,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,在存在不平衡分束器和两个不同反馈回路的情况下。
本期文章:《物理评论A》:Online/在线发表 近日,研究人员希望该方案能加深他们对EPR导引基本不对称性的理解。
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,隶属于美国物理学会, 本文提出了一项方案,中国人民解放军空军预警学院的Ben-yuan Zhou及其研究小组与华中师范大学的李高翔等人合作并取得一项新进展, By choosing appropriate feedback strengths,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。
the maximal entanglement can only be achieved through two symmetric feedback loops,并可能在量子计算和量子通信中具有潜在应用。

DOI: 10.1103/PhysRevA.110.032401 Source: https://journals.aps.org/pra/abstract/10.1103/PhysRevA.110.032401 期刊信息 Physical Review A: 《物理评论A》, 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,并与两个反馈回路相连, 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,imToken, 此外, while one-way EPR steering can only occur when both asymmetric feedback loops and an unbalanced beam-splitter are satisfied simultaneously. Furthermore,创刊于1970年,该系统内置两条非线性波导,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 ,可以有效增强纠缠和EPR导引。
