论文摘要
我们研究了两个远程巨大的磁杆导流杂种系统之间的宏观非局部纠缠的动力学生成。使用两个纤维耦合的微波腔充当连接两组宏观混合单元的相互作用通道，该单元均包含一个含有木元素（由YTTrium-Iron-Garnet球体托管）和一个超导电路Qubit。令人惊讶的是，发现更强的耦合并不一定意味着更快的纠缠产生。提出的混合系统允许存在最佳的纤维耦合强度，该强度要求最短的时间生成系统的最大纠缠。我们的理论结果被证明在当前技术可以实现的特定参数范围内。在一般环境中还可以处理噪声对系统实施的影响，这表明纠缠产生的稳健性。我们的离散可变量子样木材的纠缠理论可能会导致在各种量子信息任务中的直接应用。
We investigate dynamical generation of macroscopic nonlocal entanglements between two remote massive magnon-superconducting-circuit hybrid systems. Two fiber-coupled microwave cavities are employed to serve as an interaction channel connecting two sets of macroscopic hybrid units each containing a magnon (hosted by a Yttrium-Iron-Garnet sphere) and a superconducting-circuit qubit. Surprisingly, it is found that stronger coupling does not necessarily mean faster entanglement generation. The proposed hybrid system allows the existence of an optimal fiber coupling strength that requests the shortest amount of time to generate a systematic maximal entanglement. Our theoretical results are shown to be within the scope of specific parameters that can be achieved with current technology. The noise effects on the implementation of systems are also treated in a general environment suggesting the robustness of entanglement generation. Our discrete-variable qubit-like entanglement theory of magnons may lead to direct applications in various quantum information tasks.
