论文摘要
高度激发的Rydberg原子是量子模拟和信息处理的强大平台。在这里，我们建议原子环网络研究Rydberg激发的手性电流。这些电流由通过拉曼方案印记的相位模式控制，即使在存在下，也可以持续。根据Rydberg状态的Rabi耦合与偶极 - 偶极原子相互作用之间的相互作用，电流显示出明显不同的特征。激发以速度在时间上显示特征峰的速度传播，反映了电流的手性质。我们发现，淬灭中的时间平均电流的行为与基态电流相似。该分析为开发新方法运输原子网络中的信息铺平了道路。
Highly excited Rydberg atoms are a powerful platform for quantum simulation and information processing. Here, we propose atomic ring networks to study chiral currents of Rydberg excitations. The currents are controlled by a phase pattern imprinted via a Raman scheme and can persist even in the presence of dephasing. Depending on the interplay between the Rabi coupling of Rydberg states and the dipole-dipole atom interaction, the current shows markedly different features. The excitations propagate with a velocity displaying a characteristic peak in time, reflecting the chiral nature of the current. We find that the time-averaged current in a quench behaves similarly to the ground-state current. This analysis paves the way for the development of new methods to transport information in atomic networks.
