论文摘要
我们提出了一种有效的方法，用于在腔体雄伟系统中产生光子和声子之间的大量纠缠和不对称转向，该系统由微波炉和Yttrium Iron Garnet球形组成。通过驾驶具有蓝色二定微波炉的Yttrium Iron Garnet球体的磁通模式，磁通模式可以用作工程化的Resevoir来冷却微波腔模式的Bogoliubov模式，并通过横梁 - 分机类似于机械模式。这样，微波腔模式和机械模式被驱动到固定限制的两种模式挤压状态。特别是，可以通过相等的耗散来获得光子和声子模式之间的强双向和单向不对称量子转向。它与不对称量子转向的常规提议大不相同，在两个子系统上施加了其他不平衡的损失或噪声。我们的发现可能对扩展我们对不对称转向的基本物理的理解可能很重要，并扩展了腔体旋转的潜在应用到与设备无关的量子键分布中。
We propose an effective approach for generating significant amount of entanglement and asymmetric steering between photon and phonon in a cavity magnomechanical system which consists of a microwave cavity and a yttrium iron garnet sphere. By driving the magnon mode of the yttrium iron garnet sphere with blue-detuned microwave field, the magnon mode can be acted as an engineered resevoir cools the Bogoliubov modes of microwave cavity mode and mechanical mode via beam-splitter-like interaction. In this way, the microwave cavity mode and mechanical mode are driven to two-mode squeezed states in the stationary limit. In particular, strong two-way and one-way asymmetric quantum steering between the photon and phonon modes can be obtained with even equal dissipation. It is very different from the conventional proposal of asymmetric quantum steering, where additional unbalanced losses or noises on the two subsystems has been imposed. Our finding may be significant to expand our understanding of the essential physics of asymmetric steering and extend the potential application of the cavity spintronics to device-independent quantum key distribution.
