2019. Digital Coherent 20-Gbit/s DP-PSK Y-00 Quantum Stream Cipher Transmission over 800-km SSMF. 2019 Optical Fiber Communications Conference and Exhibition (OFC). :1—3.
We demonstrate secure fiber-optic transmission utilizing quantum-noise signal masking by 217-level random phase modulation. Masking of 157 signal phase levels at a BER of HD-FEC threshold is achieved without significant impacts on the transmission performance.
