摘要

A record-large product of data rate and transmission distance in quantum-noiseassisted cipher systems for physical layer security of fiber-optic transmission was demonstrated. The cipher system is based on symmetric-key direct-data encryption utilizing signal masking by quantum (shot) noise. The encryption is achieved by 2(16)-level phase...更多
