538 Mb/s Integrated Continuous-Variable Quantum Key Distribution System

Year: 2026

Type: conference-paper

Abstract: We demonstrate a spectrally efficient 10 GBaud continuous-variable quantum key distribution (CVQKD) system with fully photonic-integrated transmitter and receiver, achieving a high asymptotic secret key rate of 538 Mb/s over a 10 km fiber link.
