Random Coding for Long-Range Continuous-Variable QKD

Quantum Key Distribution QKD schemes are key exchange protocols based on the physical properties of quantum channels. They avoid the computational-hardness assumptions that underlie the security of classical key exchange. Continuous-Variable QKD CVQKD, in contrast to qubit-based discrete-variable...

Processing Entangled Links into Secure Cryptographic Keys

The following paper presents a holistic approach to the processing of entangled links within entanglement based quantum key distribution protocols, whose security relies on the Bell inequality. We investigate the interactions, and the collective impact, of the whole processing chain on the final...
