Project summary

This project represents a significant step forward in the development of a secure, cross-border quantum communication infrastructure that will connect Germany, Poland, and the Czech Republic. Its primary goal is to establish a trusted quantum communication network capable of transmitting sensitive data securely across national borders. By deploying Quantum Key Distribution (QKD) technologies, the project will make it possible to exchange cryptographic keys in a tamper-proof and intrusion-resistant manner. This ensures that critical information can be protected even against the potential threats posed by future quantum computers, which are expected to render many classical encryption methods obsolete. The initiative will serve a range of key national stakeholders, including government institutions, critical infrastructure operators, financial entities, research centers, and data centers. By enabling these organizations to communicate securely, the project will strengthen national and regional cybersecurity capabilities, helping to safeguard vital data and systems. Moreover, the project will extend and interconnect existing national Quantum Communication Infrastructures (QCIs) in each of the three participating countries, forming a resilient cross-border quantum backbone. This interconnected network will not only enhance cooperation among the partner nations but also serve as a model for wider European quantum communication efforts. Aligned with the broader goals of the European Quantum Communication Infrastructure (EuroQCI) initiative, the project will contribute to building a continent-wide quantum-secure network. A key aspect of the project is the integration of terrestrial quantum networks with optical ground stations, which will enable communication between ground-based quantum networks and satellites. This integration is an essential step toward realizing satellite-to-ground QKD, a technology that will eventually support global quantum communication links.

Integration of Terrestrial and Space-Based Quantum Networks

By bridging terrestrial and space-based components, the project will help lay the foundation for a pan-European and ultimately global quantum communication system. In doing so, the project will play a vital role in enhancing Europe’s digital sovereignty and cybersecurity resilience. It will ensure that Europe remains at the forefront of secure digital innovation and is well-prepared for the challenges of the quantum era. Beyond technical achievements, the project will also foster scientific collaboration, knowledge exchange, and innovation among the participating countries. Ultimately, the project supports the secure digital transformation of public services, critical industries, and research infrastructures—contributing to a safer, more connected, and technologically sovereign Europe.
