Entanglement-based QKD Equipment

Complete QKD system (entanglement-based) with two point-to-point connections and the possibility of connecting to the city's quantum network. The setup and applications of future quantum networks are important research topics at the DLR Institute for Quantum Technologies. The establishment of an in-house, entanglement-based multi-party QKD network on-site with connection to the Ulm Quantum Network follows a series of scientific goals, including: 1. fundamental research on photonic quantum network hardware; 2. information-theoretic research on secure communication, quantum authentication, and network design; 3. the development of advanced network applications, application scenarios, security tests, and countermeasures against possible attacks. 4. the execution of technology demonstrations and tests of relevant operating scenarios in the urban environment. The complete system to be delivered includes QKD equipment suitable for a three-party Quantum Key Distribution (QKD) network with two point-to-point links, consisting of a sender (Alice) and two receiver nodes (Bob 1 and Bob 2). Furthermore, key pairs must be exchangeable between all 3 parties, e.g., using Key Forwarding. Further information can be found in the attached service description (contract documents).
