论文摘要
巨型原子为无效的无熔融互动提供了一个有前途的平台，这是现代量子技术的主要任务。在这里，我们系统地研究了如何在诉诸定期耦合调制的巨型原子之间实施复杂的无脱糖相互作用和耦合点的适当安排。我们证明，在实验中可以调节的调制阶段可以编码为无熔融相互作用，因此当巨型原子构成有效的闭合环时，可以实现相位依赖性动力学。此外，我们考虑了耦合点大分离并研究其对调制参数的依赖性而产生的非马克维亚延迟效应的影响。
Giant atoms provide a promising platform for engineering decoherence-free interactions which is a major task in modern quantum technologies. Here we study systematically how to implement complex decoherence-free interactions among giant atoms resorting to periodic coupling modulations and suitable arrangements of coupling points. We demonstrate that the phase of the modulation, which is tunable in experiments, can be encoded into the decoherence-free interactions, and thus enables phase-dependent dynamics when the giant atoms constitute an effective closed loop. Moreover, we consider the influence of non-Markovian retardation effect arising from large separations of the coupling points and study its dependence on the modulation parameters.
