Abstract: Quantum key distribution is today the sole technology able to guarantee an absolutely secure solution for the cryptographic key exchange problem. Quantum key distribution, when implemented ideally, is guaranteed to be safe by the laws of quantum mechanics, and immune to eavesdropping. On the other hand, quantum key distribution is an immature, cutting-edge technology that is still being developed into a user-friendly, commercially-viable solution. This project aims to implement safe quantum communications technologies in real-world environments, by a prototypical quantum link between Italy and the island of Malta realized utilising an existing submarine telecommunication optical fibre link.

INO’s Experiments/Theoretical Study correlated:
