Real-time 10 Gbit/s-16 QAM Quantum Stream Cipher Transmission over 320 km with FPGA-based Transmitter and Receiver
Masato Yoshida, Toshihiko Hirooka, Keisuke Kasai, Masataka Nakazawa · Optical Fiber Communication Conference · 2015
We demonstrate the first real-time 10 Gbit/s-16 QAM quantum stream cipher transmission over 320 km with an FPGA-based transmitter and receiver. The random number sequence pattern was changed on-line to increase the encryption security.
