报告摘要：Rydberg atoms have attracted extensive attentions in recent years due to exaggerated properties like long lifetimes and strong interactions. They are shown in theory and experiment to promise a versatile platform for quantum information processing and quantum many-body simulation. We first review a few important advances on exotic interaction dynamics of single-photon pulses and gate strategies based on single-photon storage in cold Rydberg atoms. We then introduce two of our recent works by developing different approaches to simulate the propagation dynamics of single-photon or multi-photon pulses in cold Rydberg atoms under the EIT configuration. In one work, we show some unexpected results of single-photon interaction lacked in previous works where more approximations are used to overcome the complexity in many-body systems. In the other work, we show the nonlinear storage and retrieval of a multi-photon pulse to well recover relevant results in a recent experiment with additional nontrivial findings clarified.
