Abstract :
For the unconditional secure quantum key distribution (QKD), Faraday-Michelson interferometers (FMI) based system provide an intrinsic way to avoid the influence from the birefringence effect through fiber. In our paper, we designed an electronics system for the FMI-based QKD system with high repetition rate. The system was tested in 125 MHz repetition rate for more than 16 hours and obtained a quantum bit error rate less than 4%, which is to our knowledge the highest repetition rate result for FMI-based QKD system.
