Quantum key distribution (QKD) is an innovative technology allowing information-theoretically-secure key sharing among distant users relying only on fundamental rules of quantum physics, without assumptions about the computational power of the attacker. This work presents the architecture of the Rome QKD Metropolitan Area Network (QMAN), the different layers required to sustain such network, including the Key Management System developed by Leonardo and the interconnection with the Italian Quantum Backbone to intregrate this network in the EuroQCI program. The Rome QMAN is a quantum-safe hybrid network, made up of several nodes that are connected with both commercial fibre and a free-space link.
