Quantum cryptography in critical communications

The "Quantum Cryptography in Critical Communications" project was born to transmit critical information in an ultra-secure way based on a system of quantum keys. A quantum communication link has been successfully established, through point-to-point fibre optics over a distance of 30 km. This first connection using quantum cryptography is the embryo of the future metropolitan network, connected to the quantum, national and pan-European Internet. The project has been promoted and financed with €1.2M by the Department of the Vice-Presidency and Digital and Territorial Policies and coordinated by ICFO.
