| 摘 要： | 我们采用周期极化KTP晶体为非线性介质，通过光学参量振荡器运转于阈值以下的简并参量振荡过程，产生了单模正交压缩真空态光场，在泵浦功率为123mW，Local光功率为842uW，晶体温度为32．1摄氏度时我们使用平衡零拍探测法测得输出场噪声功率低于散粒噪声基准3．41dB。

| Abstract: | Based on adiabatic passage, we propose a scheme to implement quantum transfer of an unknown atomic state. In our scheme, we utilize photons for ideal quantum transmission between two cavities with the success probability approaches 1. Meanwhile, the scheme is robust against the effects of atomic spontaneous emission. It will be useful for transferring quantum information among spatially distant atoms. |
