量子保密通信因其具有理论上的无条件安全性,在国防、金融、政务、商业等领域的应用潜力巨大,同时也对通信网络提出了一定的要求。在研究量子保密通信的基础上,提出了开放型量子保密通信的系统架构;同时为了更好地与现有通信系统融合,提出了一种量子密钥分发(QKD)系统与大容量光通信系统共纤传输方案,并通过实验验证了QKD系统和80×100 Gbit/s DWDM系统共纤传输的可行性,在超过100 km共纤(G.654超低损光纤)传输条件下同时实现了QKD成码率超1 kbit/s和8 Tbit/s DWDM系统无误码传输。
Based on the study of the mechanism of quantum encryption system
the system architecture of open quantum cryptographic communication was proposed.In order to better integrate with the existing communication system
a quantum key distribution (QKD) system and a large capacity optical communication co-fiber transmission scheme were proposed
and the QKD system and 80×100 Gbit/s DWDM were verified through experiments.The feasibility of the system common fiber transmission was realized under the condition of ultra 100 km common fiber transmission
the QKD bit rate >1.0 kbit/s and 8 Tbit/s DWDM system without error bit and the practical threshold of the commercial encryption device key rate>1.0 kbit/s was achieved.
