Secure Unrepeated Fiber Transmission with Quantum Deliberate Signal Randomization on Y-00 Protocol
Fumio Futami, Ken Tanizawa, Kentaro Kato, Yuki Kawaguchi, Shin Sato · 2023
We demonstrate security-enhanced 10-Gbit/s PSK Y-00 cipher transmission with deliberate signal randomization driven by a quantum random number generator in a 362 km ultra-low-loss fiber link without optical amplifiers. High security is achieved at high optical powers.
