Thought Leadership
A milestone in quantum research: KIT has put a special fiber optic test track into operation. The 20-kilometer connection between the two campuses enables research into quantum networks and tap-proof communication.
Quantum technology for secure communication
The 20-kilometre-long fiber optic link connects specially equipped laboratories with highly coherent lasers and cryostats. With a core diameter of just 9 micrometers, the fiber transports quantum keys based on physical laws. This technology is considered future-proof as – unlike current encryption methods – it can also withstand attacks by quantum computers.

Research platform for quantum communication
“With the fibre-optic test track, we now have a platform to further develop quantum key distribution, carry out fundamental characterizations and integrate it into classical communication,” explains project leader Professor David Hunger from the KIT Institute of Physics. The team is working together with the startup KEEQuant, among others, to make quantum cryptography more efficient.
Paving the way for the quantum internet
Another focus is on the development of a quantum network. Quantum repeaters for long-distance transmission are being created through the development of quantum memories and their entanglement. This technology should also enable the networking of quantum computers in the future.
The test track is part of the Cluster of Excellence initiative “Chem4Quant” and the BMBF project Quantenrepeater.Net. It underlines the importance of the KIT as a research location for quantum technologies.
