论文摘要
我们在波导QED方案中研究了巨型原子的动力学，在该场景中，原子夫妇通过两个位点与耦合的谐振波导。对于单个巨型原子设置，我们发现可以通过调整其尺寸来调整原子耗散率。对于两个巨型原子系统，波导将诱导可控的个体和集体耗散以及有效的原子间耦合。结果，我们可以从理论上实现强大的纠缠状态制备和非转录激发演变。我们希望我们的研究可以根据光子和声学波导设置应用于量子信息处理。
We investigate the dynamics of giant atom(s) in a waveguide QED scenario, where the atom couples to the coupled resonator waveguide via two sites. For a single giant atom setup, we find that the atomic dissipation rate can be adjusted by tuning its size. For the two giant atoms system, the waveguide will induce the controllable individual and collective dissipation as well as effective inter-atom coupling. As a result, we can theoretically realize the robust entangled state preparation and non-reciprocal excitation evolution. We hope our study can be applied in quantum information processing based on photonic and acoustic waveguide setup.
