Quantum Communications

This research line targets the study of quantum-safe communications. Although new cryptographic protocols like post-quantum cryptography are already available and standardized, the main focus is on the practical use of quantum key distribution. This includes its integration into traditional optical communication networks with co-propagation with data channels, multi-domain issues in the vertical and horizontal domains, and time and frequency signals. It also focuses on reliable and resilient quantum key distribution networks, extending their reach through hybrid solutions and improving secure relay privacy. Additionally, it explores new quantum enabled high precision time and frequency distribution.
