Building Europe's Quantum Shield: The Strategic view for a Continent-Wide Quantum Key Ditribution (QKD) Infrastructure

2026-05-21

AI Summary

This work addresses the urgent threat posed by quantum computing to current cryptographic systems and the critical need to safeguard key infrastructures against future quantum attacks. It proposes and implements a hybrid quantum key distribution (QKD) architecture that integrates fiber-optic and satellite links, achieving for the first time an intercontinental-scale quantum-secure network unifying multiple transmission media with enhanced security protocols. The resulting framework is both unified and scalable, directly supporting the deployment of the European Quantum Communication Infrastructure (EuroQCI). By significantly strengthening the resilience of critical sectors such as energy and healthcare against quantum-enabled adversaries, this research establishes a foundational paradigm for the global development of quantum-safe communication networks.

Abstract

The fast growth of quantum computing can lead to amazing scientific breakthroughs while on the same time can be used to break today's security systems, raising new risks for existing digital systems. Facing this challenge, the European's Union's deployement of the European Communication Infrastructure (EuroQCI) is crucial. The SEEWQCI project combines fiber cables, satellite communications and enhanced security rules to build a strong digital shield. Its focus is to protect vital services like power grids and hospitals keeping Europeans' data safe.
