Quantum-Inspired Encryption Using Displacement Operators in Coherent Optical Communications
Mostafa Khalil, Adrian Chan, Lawrence R. Chen, David V. Plant, Randy Kuang · 2024
We demonstrate experimental results of a physical layer encryption technique based on displacement operators in coherent optical transmission systems. The system is tested over 80 km of SSMF using 4/16/32QAM at 56 GBd.
