INRiM solutions for QKD real-world network implementations

Quantum key distribution (QKD) is a technology that allows sharing secret cryptographic keys between two distant users (Alice and Bob), whose intrinsic security is guaranteed by fundamental principles of quantum mechanics. QKD is a mature technology: in Europe, all the 27 EU member states are working in a European Commission initiative (EuroQCI) to design, develop and deploy a quantum communication infrastructure composed by several national networks. For example, in Italy, the Italian Quantum Backbone will be used as a quantum communication testbed within the project QUID, that is in charge of the realization of the Italian part of EuroQCI.
