The hybrid microwave optomechanical-magnetic system has recently emerged as a promising candidate for coherent information processing because of the ultrastrong microwave photon-magnon coupling and the long life of the magnon and phonon. As a quantum information processing device, the realization of single excitation holds special meaning for the hybrid system. In this paper, we introduce a single two-level atom into the optomechanical-magnetic system and show that an unconventional blockade due to destructive interference cannot offer a blockade of both the photon and magnon. Meanwhile under the condition of single excitation resonance, the blockade of the photon, phonon, and magnon can be achieved simultaneously even in a weak optomechanical region, but the phonon blockade still requires the cryogenic temperature condition.

由两个能级原子引起的光子，声子和磁振子的同时封锁

由于超强微波光子-磁振子耦合以及磁振子和声子的长寿命，混合微波光机电磁系统最近已成为相干信息处理的有希望的候选者。作为量子信息处理设备，单激励的实现对于混合系统具有特殊的意义。在本文中，我们将单个二级原子引入光机电磁系统，并表明由于相消干涉而引起的非常规阻挡不能同时提供光子和磁振子的阻挡。同时，在单激发共振的条件下，即使在弱的光机械区域中也可以同时实现对光子，声子和磁振子的阻挡，但是声子的阻挡仍然需要低温条件。
