论文摘要
最近，发现了耗散耦合，该耦合发展并扩大了控制和利用光线相互作用的方法。在这里，我们提出了一个计划，以在耗散耦合的系统中生成三方$ w $状态，其中一个Qubit和两个谐振器同时与公共储层交互。使用适当的参数，我们发现$ W $状态是系统的黑暗状态。通过驾驶量子，散发耦合的系统将从基态发展到三方$ W $州。由于初始状态是系统的基础状态，并且不需要测量，因此我们的方案在实验中很容易实施。此外，$ w $状态与普通储层的脱离，因此一生很长。该方案适用于广泛的耗散耦合系统，我们专门说明了如何通过使用此方案在混合量子型 - Photon-Magnon系统中准备$ W $状态。
Very recently, dissipative coupling was discovered, which develops and broadens methods for controlling and utilizing light-matter interactions. Here, we propose a scheme to generate the tripartite $W$ state in a dissipatively coupled system, where one qubit and two resonators simultaneously interact with a common reservoir. With appropriate parameters, we find the $W$ state is a dark state of the system. By driving the qubit, the dissipatively coupled system will evolve from the ground state to the tripartite $W$ state. Because the initial state is the ground state of the system and no measurement is required, our scheme is easy to implement in experiments. Moreover, the $W$ state decouples from the common reservoir and thus has a very long lifetime. This scheme is applicable to a wide class of dissipatively coupled systems, and we specifically illustrate how to prepare the $W$ state in a hybrid qubit-photon-magnon system by using this scheme.
