Quantenrepeater.Net
Secure Communication through Quantum Networks
In the research consortium “Quantenrepeater.Net” – or QR.N for short – 42 project partners from research and industry are working together to achieve significant advances in the development and implementation of Quantum Networks.
On the Way to Quantum Networks: Demonstration of Teleportation over a Fiber Link
Achieving quantum-physical end-to-end security in communication and securely linking Quantum Computers are among the most important long-term objectives in the development of Quantum Technologies in Germany. This level of security can only be realized through the use of Quantum Repeaters. One of QR.N’s main goals is to demonstrate the fundamental functionalities of Quantum Repeaters on test tracks outside of protected laboratory environments.
The QR.N consortium is divided into four platforms with different research focuses, each consisting of partners from various universities, research institutions, and industrial companies. Together, all partners carry out the research work of the consortium.
