Bavaria–Austria Quantum Communication Infrastructure
The Bavaria–Austria Quantum Communication Infrastructure (BAT-QCI) project develops a secure cross-border quantum communication network between Austria and Germany.
It will deploy a quantum key distribution (QKD) link of roughly 500 km connecting Vienna and Munich through several trusted nodes.
The project also prepares the ground infrastructure for the EAGLE-1 quantum communication satellite by installing an optical ground terminal in Vienna.
A multi-domain key management system and hybrid cryptographic methods will be developed to integrate terrestrial and satellite quantum networks securely. Overall, the project contributes to the EuroQCI initiative, aiming to strengthen secure communication and digital sovereignty across Europe.
Abstract
The project is part of the European EuroQCI initiative, which aims to create a secure quantum communication infrastructures in Europe. This effort represents a major step toward protecting sensitive data and strengthening digital sovereignty within the European Union.
The project seeks to connect Vienna and Munich through a quantum key distribution (QKD) network of approximately 500 km, supported by several trusted nodes and a cross-border connection near Salzburg. In parallel, the project will prepare the ground segment for Europe’s first quantum communication satellite, EAGLE-1, by installing an optical ground terminal in Vienna.
To achieve these goals, the project will develop a multi-domain key management system to enable seamless integration between terrestrial and satellite-based quantum networks. It will ensure compatibility with European and ETSI standards and promote interoperability and cross-border use cases – such as secure communication between governmental sites in Austria and Germany – which will contribute to building a resilient and trusted European quantum network. The consortium will implement advanced monitoring, hybrid cryptographic methods, and define requirements for security operation centres. Through close collaboration with governmental stakeholders and other EuroQCI projects, the project plays a central role in shaping Europe’s future secure communication landscape.
The project is coordinated by a leading research institute and unites a consortium with complementary strengths. It brings together scientific expertise, advanced cybersecurity knowledge, and hands-on experience in secure IT infrastructures. Together, this consortium combines research excellence, security expertise, and operational capabilities to ensure successful the project’s successful implementation.
