We present a scheme to implement a steady optical-photon-and-magnon entanglement in a hybrid optomagnonics-mechanical system by adiabatical elimination of the auxiliary microwave (MW) cavity and effective laser cooling of a delocalized Bogoliubov mode. The system consists of a magnon, an optical and a MW cavities, and a mechanical vibrator. To achieve a direct entangling interaction between the magnon and the optical photon, we drive the optical cavity and magnon at the red and blue sideband associated with the mechanical resonator, respectively. In particular, by eliminating the MW cavity and optimizing the relative ratio of effect couplings, rather than merely increasing their magnitudes, we achieve a strong entanglement between optical photons and magnons.

在光电子学-机械系统中产生光子和磁子纠缠

我们提出了一个方案，通过绝热消除辅助微波（MW）腔并有效地冷却Bogoliubov模式的激光，在混合光电子机械系统中实现稳定的光子和磁子纠缠。该系统由一个磁振子，一个光学腔和一个MW腔以及一个机械振动器组成。为了实现磁振子和光学光子之间的直接纠缠相互作用，我们分别在与机械谐振器相关的红色和蓝色边带驱动光腔和磁振子。特别是，通过消除MW腔并优化效应耦合的相对比率，而不仅仅是增加其幅度，我们实现了光子与磁振子之间的强力纠缠。
