Experimental Demonstration of Finite-Size General Security Via Discrete-Modulated CVQKD with Real Time Postprocessing

Continuous-variable quantum key distribution CVQKD is compatible with telecommunication infrastructure, but implementing composable security with experimentally practical resources has remained challenging, particularly for discrete-modulated DM protocols. We report the first experimental...

Semi-Device-Independent Quantum Random Number Generator Resistant to General Attacks

Quantum random number generators QRNGs produce true random numbers based on the inherent randomness of quantum theory, rendering them a foundational segment of quantum cryptography. Distinguished from trusted-device QRNGs whose security depends on characterized devices, semi-device-independent...
