We present to use the squeezed light and the thermal effect to induce the one-way steering of magnon modes from two separated yttrium–iron–garnet spheres respectively placed in two microwave cavities. Based on the squeezed-reservoir engineering, the reduced master equation of magnon modes is derived by adiabatically eliminating the variables of cavity modes in the bad-cavity limit. Our results reveal that the steady-state steerable correlation of distant macroscopic objects is effectively achieved, and the steering direction could be tunable with the choice of the experimental parameters such as the squeezing degree, the coupling strengths, and the thermal magnon occupations. The responsible mechanism is due to the delicate interplay between the squeezing reservoir and the original dissipative process of the cavity fields. The striking feature of our scheme is that it relaxes the requirement of accurate control of the system. Moreover, the scheme is focused on the asymmetric Einstein–Podolsky–Rosen steering of macroscopic magnons and it could be extended to more magnon modes, which may provide a novel method for studying the macroscopic quantum phenomena and devising the active quantum information devices.

我们提出使用压缩光和热效应从分别放置在两个微波腔中的两个分离的钇 - 铁 - 石榴石球体中诱导磁振子模式的单向转向。在挤压油藏工程的基础上，通过在坏腔极限下绝热消除腔模变量，推导了磁振子模式的简化主方程。我们的结果表明，有效地实现了远处宏观物体的稳态可转向相关性，并且转向方向可以通过选择挤压度、耦合强度和热磁子占据等实验参数进行调节。负责的机制是由于挤压储层和腔场的原始耗散过程之间微妙的相互作用。我们方案的显着特点是放宽了对系统精确控制的要求。此外，该方案侧重于宏观磁振子的不对称爱因斯坦-波多尔斯基-罗森转向，它可以扩展到更多的磁振子模式，这可能为研究宏观量子现象和设计有源量子信息器件提供一种新方法。
