Abstract

Enhancement of Quantum Entanglement in Cavity–Magnon systems

In article number 2400221, Rong-Can Yang, Hong-Yu Liu, and co-workers focus on the enhancement of quantum entanglement and quantum steering in cavity–magnon hybrid systems using quantum coherent feedback (QCFB) control loops, as shown in the cover image. In the scheme, SQUID is applied to realize Josephson parametric amplification, driving the 3D microwave cavity with two-photon field. Moreover, quantum correlation of the two magnon modes is indirectly established through the magnetic dipole interaction, and the enhancement is implemented effectively with QCFB.

增强腔磁系统中的量子纠缠在第 2400221 号文章中，杨荣灿、刘洪宇及其合作者重点研究了利用量子相干反馈（QCFB）控制环增强腔磁混合系统中的量子纠缠和量子转向，如封面图片所示。在该方案中，SQUID 被用于实现约瑟夫森参量放大，用双光子场驱动三维微波腔。此外，还通过磁偶极子相互作用间接建立了两个磁子模式的量子相关性，并利用 QCFB 有效地实现了增强。

期刊介绍： Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
