A Single-channel 40 Gbit/s Digital Coherent QAM Quantum Stream Cipher Transmission over 480 km

摘要：

　　We demonstrate a single-channel 40-Gbit/s QAM quantum stream cipher transmission over 480-km.By using a multi-bit encoded scheme and digital coherent transmission techniques,record data capacity and transmission distance of secure optical communication have been successfully realized.
