QUID

The project QUID proposes to start the deployment of the Quantum Communication Infrastructure (QCI) in Italy. QUID deploy systems and networks on the national territory to test quantum distribution of cryptographic keys, with attention to integrating them with existing communications. On the other hand, QUID foster the uptake of these systems and networks from use cases. QUID is based on the deployment of several Nodes in Metropolitan Area Networks based on Discrete Variable QKD, connected by a fibre backbone. During the project, several nodes will test QKD systems, while long-distance deployment will use techniques based on Trusted Nodes, or Twin Field QKD (Untrusted Nodes).

QUID will connect also sites relevant for interconnection with the space segment of the European QCI. Last, since QKD still offers relevant possibilities of innovation, QUID devotes activities towards improving QKD features, in particular high-rate, use of innovative fibres, and the use of free-space QKD, to be implemented for mobility and where fibre is not present. QUID consortium is composed of leader Italian companies in the field, integrating systems, manufacturing QKD devices, operating telecommunication networks, and offering cyber security integrated solutions.

As well, the main research institutes involved in quantum communication in terrestrial and space segment are present, as well as five among the more relevant universities, committed to innovation and training.
