Next-Generation QKD Systems

About this grant

Expected Outcome: This action will strengthen Europe's strategic autonomy in quantum-secure communications by advancing core QKD technologies and integration capabilities. Expected results include: Development and demonstration of next-generation QKD systems, with a focus on cost-effectiveness and integration, with specific measurable improvements in one of the following parameters or features: (i) key rate (>1 Mbps over metropolitan distances), (ii) operational coverage of a network at the regional scale, >300 km for fibre-based QKD, including e.g. twin field and free-space links also for non-wired segments and for redundancy, (iii) development and demonstration of advanced quantum cryptographic protocols beyond QKD with provable security advantage over classical cryptographic systems. Implementation of hybrid quantum-classical cryptographic frameworks combining QKD and post-quantum cryptography (PQC), tested on clearly defined real-world applications. Integration of quantum communication components with network equipment and orchestration systems (e.g., software-defined networking). Validation of QKD-based security in high-priority use cases beyond EuroQCI infrastructure, including: Critical infrastructure monitoring (e.g., energy grid telemetry), Long-term secure cloud storage, Industrial control systems (e.g., transport, manufacturing), Secure multi-site enterprise communications. Strengthened European supply chain through the development of certifiable, standardised, and... EU contribution per project: EUR 21,000,000 to EUR 24,000,000 (euros, not converted).
