摘要:

利用电磁感应透明性成功地证明了压缩真空的存储和恢复。利用强控制光,将930 ns的压缩真空脉冲以相干态入射到激光冷却的~(87)Rb原子上。当压缩真空脉冲在冷原子中被减速和空间压缩时,控制光被关闭。在3us的存储之后,再次打开控制光并且恢复压缩真空,如使用时域零差方法所确认的。

英文摘要:

Storage and retrieval of a squeezed vacuum was successfully demonstrated using electromagnetically induced transparency. 930ns of the squeezed vacuum pulse was incident on the laser cooled 87Rb atoms with an intense control light in a coherent state. When the squeezed vacuum pulse was slowed and spatially compressed in the cold atoms, the control light was switched off. After 3us of storage, the control light was switched on again and the squeezed vacuum was retrieved, as was confirmed using the time-domain homodyne method.
