Mbps-Key-Rate Continuous-Variable Quantum Key Distribution with Integrated Modulator and Receiver on Silicon Photonic Chips
We report a continuous-variable quantum key distribution system with a silicon photonic modulator and receiver, achieving a 4.7 Mbps secret key rate at 15.5 km through optimized on-chip operating point control and digital signal processing.
