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。将时间宽度为930 ns的压缩真空脉冲与强控制光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。储存3 μ s后，再次打开控制光，并恢复压缩真空，如使用时域零差法所证实的。
Storage and retrieval of a squeezed vacuum was successfully demonstrated using electromagnetically induced transparency. The squeezed vacuum pulse having a temporal width of 930 ns was incident on the laser cooled (87)Rb 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 3 mu s of storage, the control light was switched on again, and the squeezed vacuum was retrieved, as was confirmed using the time-domain homodyne method.
