The “DemoQuanDT” project aims to develop and demonstrate a secure and vendor-independent quantum communication network in Germany. In light of the advancing digitization of critical infrastructure such as power and water utilities, as well as communication networks, current encryption technology is vulnerable to quantum computers. Quantum communication provides a solution to ensure information transmission that is resistant to quantum computers.
The project has achieved significant milestones, including the procurement of Quantum Key Distribution (QKD) modules from various European manufacturers and the establishment of a state-of-the-art laboratory for testing QKD hardware. Additionally, DemoQuanDT works on developing an architecture and secure scenarios for key communication. In-house Key Management Systems are being developed to ensure network security.
A major step forward is the planning and construction of a test route between Berlin and Bonn in a real-world environment involving multiple QKD hardware manufacturers. Existing fiber-optic infrastructure and regular operational sites are being utilized. The presentation of this route in a showcase will be a highlight, demonstrating all the necessary components and processes for the practical operation of a QKD network, including error resilience.
“DemoQuanDT” could lay the foundation for a nationwide quantum communication network, bolstering cybersecurity across the country.
