摘要
我们建议由把一台 rf 超导的量干扰设备(rf 枪乌) 放在一个单个模式的微波洞准备洞模式的 Schrödinger-cat 状态的一个潜在的计划。由适当地关于放射地调整 detuning 和力量，我们显示出怎么产生单个模式的 Schrödinger-cat 状态。概括我们讨论 engtangled 的产生的这个方法协调状态。我们的计划的试验性的可行性在洞腐烂的考虑下面被讨论。
We propose a potential scheme of preparing Schrodinger-cat state of the cavity mode by placing an rfsuperconducting quantum interference device （rf-SQUID） in a single-mode microwave cavity. By properly adjusting the detuning and the strength regarding the radiation fields, we show how to generate single-mode Schrodinger-cat state. Generalizing this method we discuss the generation of the engtangled coherent states. The experimental feasibility of our scheme is discussed under consideration of the cavity decay.
