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...

Multichannel Hybrid Quantum Cryptography for Submarine Optical Communications

We present a multichannel hybrid quantum cryptography approach intended for submarine quantum optical communications between Alice and Bob separated a distance beyond the current QKD possibilities, each located on a coastline. It is based on the difficult of a simultaneous access to $M$ optical...
