Intensity modulator for secure, stable, and high-performance decoy-state quantum key distribution

Abstract The decoy-state method substantially improves the performance of quantum key distribution (QKD) and perfectly solves crucial issues caused by multiphoton pulses. In recent years, the decoy-state method has occupied a key position in practicality, and almost all the QKD systems have employed...
