QUID (Quantum Italy Deployment) is set to initiate the deployment of the Quantum Communication Infrastructure (QCI) in Italy. QUID’s primary focus is on deploying systems and networks nationwide to test quantum communication technologies, with a specific emphasis on the quantum distribution of cryptographic keys and integration with existing communication systems. Simultaneously, QUID aims to encourage the adoption of these systems and networks through various use cases.
The QUID project is centered around deploying multiple nodes in Metropolitan Area Networks utilizing Discrete Variable Quantum Key Distribution (QKD) connected by a fiber backbone. Throughout the project, various nodes will test QKD systems, employing techniques such as Trusted Node and Twin Field QKD (for Untrusted Nodes) for long-distance deployment. QUID will also establish connections with sites crucial for interconnection with the space segment of the European QCI.
Recognizing the ongoing possibilities for innovation in Quantum Key Distribution, QUID is dedicated to enhancing QKD features, focusing on aspects such as high-rate capabilities, the use of innovative fibers, and the implementation of free-space QKD—particularly in scenarios where mobility is required or where fiber infrastructure is unavailable.
To establish a robust ecosystem, the QUID consortium comprises leading Italian companies specializing in systems integration, QKD device manufacturing, telecommunication network operations, and comprehensive cybersecurity solutions. Additionally, the consortium includes major research institutes involved in both terrestrial and space quantum communication, along with five prominent universities committed to fostering innovation and providing training opportunities.
