论文摘要
提出了使用AC Stark效应的虚拟磁场的量子状态光存储，以结合使用室温原子蒸气的高整体存储效率和较大的带宽。在这种方法（称为AC Stark梯度回声记忆（ASGEM））中，已证明有可能使用D1 rubidium系列使用纳米秒的AC Stark脉冲（约127 THz），并创建一种原子媒体，并有可能将光子储存的光子与GHZ带量一起存储，并具有大约一个GHZ带量，并具有大约一个比90％的ghz带量。基于三级Maxwell-Bloch方程的效率的轮廓图作为梯度场强度和光学深度的函数，以更好地理解实验参数优化。
A quantum state light-storage, using a virtual magnetic field through the ac Stark effect is proposed to combine the high overall storage efficiency and large bandwidth employing room temperature atomic vapor. In this approach, which was called the ac Stark Gradient Echo Memory (ASGEM), it has been shown the possibility to employ about a nanosecond ac Stark pulse far detuned (about 127 THz) from D1 line of rubidium and create an atomic media with the possibility to store a photon with about a GHz bandwidth with storage and retrieval efficiency of more than 90%. A contour plot of efficiency as a function of gradient field strength and optical depth, based on three-level Maxwell- Bloch equations, simulated for a better understanding of experimental parameter optimization.
