ground station

the results show that it is feasible to implement quantum key distribution between a ground station and a satellite in a low earth orbit and that it is the detector dark noise and the space optical environment that limit the link distance for free-space quantum key distribution.

结果表明，在低轨卫星地面站间进行量子密钥分配是可行的，限制自由空间量子密钥分配链路距离的主要因素是探测器暗噪声和空间光学环境。
