| 摘 要： | 采用海森堡-朗之万方法理论研究了Tripod型双电磁诱导透明原子系统中压缩态探针场的传输特性.研究结果表明:通过双透明窗口压缩光可实现双通道传输,且每个通道可以被独立操控;当两束耦合场的频率失谐相等时,输出探针场的压缩度可以得到更好的保持.此外,输出探针场的压缩度可以通过耦合场的拉比频率、原子的光学厚度和基态退相干率以及探测频率来操控.该研究结果为进一步优化多通道量子存储提供依据.

Squeezing Propagation through Double Electromagnetically Induced Transparency in a Tripod-Type Atomic System |
| |
| Abstract: | The squeezed probe light transmission characteristic through a double electromagnetically induced transparency in tripod-type atomic system was investigated by using the Heisenberg-Langevin approach.The results show that,the squeezing can survive in two electromagnetically induced transparency windows independently.The output squeezing in tripod-type atoms can be better preserved when the frequency detunings of two coupled fields are equal.It is found that the output squeezing is also determined by the Rabi frequency of coupling fields,optical depth and dephasing rate of atoms,and detection frequency.This study has a potential application in multi-channel quantum memory for quantum network. |
