论文摘要
我们提出了一种新型的腔度光 - 磁化杂种系统，以在光学和微波域中的多个量子载体（例如镁，机械谐振器和腔光子）之间产生纠缠。将两个Yttrium铁石榴石（YIG）球嵌入两个单独的微波腔中，由公共机械谐振器连接。由于微波腔是分开的，因此可以独立调整两个YIG球体的铁磁谐振频率以及空腔频率。我们表明，可以通过实验可及的参数来实现纠缠。由于光腔实现的机械冷却过程，纠缠与环境热噪声是可靠的。不同载体之间的最大纠缠是通过优化系统参数来实现的。分离腔的个体可调性使我们能够独立控制不同子系统的纠缠特性，并在一个系统中建立具有不同纠缠特性的量子通道。这项工作可以在量子计量和量子信息任务中提供有希望的应用。
We present a novel cavity opto-magno-mechanical hybrid system to generate entanglements among multiple quantum carriers, such as magnons, mechanical resonators, and cavity photons in both the optical and microwave domains. Two Yttrium iron garnet (YIG) spheres are embedded in two separate microwave cavities which are joined by a communal mechanical resonator. Because the microwave cavities are separate, the ferromagnetic resonate frequencies of two YIG spheres can be tuned independently, as well as the cavity frequencies. We show that entanglement can be achieved with experimentally reachable parameters. The entanglement is robust against environmental thermal noise, owing to the mechanical cooling process achieved by the optical cavity. The maximum entanglement among different carriers is achieved by optimizing the parameters of the system. The individual tunability of the separated cavities allows us to independently control the entanglement properties of different subsystems and establish quantum channels with different entanglement properties in one system. This work could provide promising applications in quantum metrology and quantum information tasks.
