实用的昼夜10 km自由空间量子密钥分发
Practical free-space quantum key distribution over 10 km in daylight and at night
摘要：
我们已经证明了量子密钥分发（QKD）在10公里，1大气层范围内在白天和夜间。用于初始化安全通信设备的加密密钥所需质量的秘密随机比特序列以实际安全的实际速率传输。通过确定决定系统保密效率的物理参数，我们推断，在这些和其他大气和仪器条件下，自由空间QKD将在更长的范围内实用。
英文摘要：
We have demonstrated quantum key distribution (QKD) over a 10-km, 1-airmass atmospheric range during daylight and at night. Secret random bit sequences of the quality required for the cryptographic keys used to initialize secure communications devices were transferred at practical rates with realistic security. By identifying the physical parameters that determine the system's secrecy efficiency, we infer that free-space QKD will be practical over much longer ranges under these and other atmospheric and instrumental conditions.
