论文摘要
我们研究了耦合腔体系中宏观微波磁通模式之间的遥远纠缠产生。腔通过光纤连接，这需要在腔体内使用频率转换。转换器可以通过像有效的三级系统一样通过稀土掺杂晶体实现。分析系统研究了系统的纠缠动力学，并提出了一种主动的最佳控制方法，其中可能会在给定的演变时间下生成最大纠缠的铃铛状态。系统动态及其控制也已在通用的非马克维亚开放系统框架中进行了研究，并且发现生成的纠缠在环境噪声上是可靠的。
We study the remote entanglement generation between macroscopic microwave magnon modes in a coupled cavity system. The cavities are connected via an optical fiber, which necessitates the use of a frequency conversion inside the cavity. The converter may be implemented via a rare-earth doped crystal acting like an effective three-level system. The entanglement dynamics of the system is analytically studied, and an active optimal control method is also proposed where one may generate maximally entangled Bell states on demand with a given evolution time. The system dynamics and its control have also been studied in a generic non-Markovian open system framework, and the generated entanglement is found to be robust against environmental noises.
