A €6m German research project aims to move quantum communication networks out of the lab and into real-world, multi-node infrastructure.
Currently, quantum communication can only take place through a direct link between two specific points. The QCyber project, led by the University of Stuttgart, aims to develop secure quantum network applications for multiple users.
Professor Stefanie Barz of the University of Stuttgart, who is coordinating the project, said: “Quantum networks studied so far typically connect only two users. But in practice, often multiple parties need to communicate securely at the same time.”
The €6m QCyber project, which will run until the end of 2028, is being funded by the German Federal Ministry of Research, Technology and Space over three years. It will field-test secure quantum applications across a real fibre-optic network in Stuttgart, connecting up to six nodes over distances of up to 20km.
The project will encompass a wide range of applications that enable group...
