摘要
利用光子回声协议研究光压缩态的量子存储方案。研究发现,当制备的原子系综有较大光学深度时,入射光信号的压缩特性就可被完美地记录于原子系综并重新构建于输出光信号。该方案为实现高效的光压缩态存储提供了一个确实可行的方法。
The quantum memory for squeezed optical field based on photon echo protocol is studied. It is shown that, as long as the optical depth of the atomic ensemble is sufficiently large, squeezed properties of the incident optical field can be perfectly preserved in atoms, and can also be reconstructed in the output optical field. Therefore, the investigation provides hopeful possibilities for the realization of efficient quantum memory for squeezed light based on photon echo.
