论文摘要
我们展示了如何在混合光电气 - 磁系统中产生光和微波之间的固定纠缠，该系统主要由微波炉，Yttrium Iron Garnet（YIG）球体和纳米纤维组成。纳米纤维中的光学模式可以通过自旋轨道相互作用（在YIG球体中）与少镁模式相互作用，而在YIG球体中，这些模式可以与镁模式相互作用，而微波炉型光子光子和镁镁和镁却同时通过磁性偶极相互作用耦合。在合理的参数制度下，可以生成相当多的纠缠，并且还显示了在温度下的持久性。预计我们的工作将为建立更先进和全面的量子网络以及用于快速开发的量子技术的镁和研究宏观量子现象提供新的视角。
We show how to generate stationary entanglement between light and microwave in a hybrid opto-electro-magnonical system which mainly consists of a microwave cavity, a yttrium iron garnet (YIG) sphere and a nanofiber. The optical modes in nanofiber can evanescently coupled to whispering gallery modes, that are able to interact with magnon mode via spin-orbit interaction, in YIG sphere, while the microwave cavity photons and magnons are coupled through magnetic dipole interaction simultaneously. Under reasonable parameter regimes, pretty amount of entanglement can be generated, and it also shows persistence against temperature. Our work is expected to provide a new perspective for building more advanced and comprehensive quantum networks along with magnons for fast-developing quantum technology and for studying the macroscopic quantum phenomena.
