At the DLR Institute of Quantum Technologies (DLR-QT) in Ulm, we develop precision instruments for space applications based on quantum technologies and bring them to prototype maturity together with industry. In addition, we are driving forward the transfer to aviation, digitalization, energy, security and transport. Together with the DLR Institute of Satellite Geodesy and Inertial Sensing (SI) in Hanover and the DLR Galileo Competence Center (GK) in Oberpfaffenhofen, we play a pioneering role in quantum technology research and application fields. The research work of our four core departments Quantum Metrology, Quantum Information and Communication, Quantum Nanophysics and Electromagnetic Quantum Sensors is complemented and supported by the three cross-sectional departments Quantum Engineering, Integration of Micro- and Nanosystems and Theoretical Quantum Physics. We have an interdisciplinary approach: Theoretical basic research and experimental tests meet engineering implementation.
