Quantum technologies of the second generation can be applied in a many areas where they enable the improvement of known technologies and open up fundamentally new possibilities. Examples are: Quantum communication makes it possible to secure communication even against future, currently unknown attacks; the increased performance of quantum computers due to the parallelization of calculations puts the solution of previously unsolved problems within reach; quantum simulators make it possible to simulate the behavior of complex quantum systems with the help of other, highly controlled quantum systems. Quantum technology components such as coherent optical memories promise new neuromorphic computer architectures for artificial intelligence and machine learning capabilities. 

Our scientific mission at DLR and TU Berlin is to advance the second-generation quantum information technologies. The research interest of the FITS group is focused on the fundamentals of quantum communication and optical postdigital computers. In the domain of quantum communication, we are interested in quantum repeater networks. In the domain of postdigital computer we investigate optical neural networks for machine learning and photonic quantum computing architectures.

All of these applications  are based on the one hand on single photon sources and on the other hand on quantum memories as key components. For both, but especially for the latter, there is still a considerable need for research before "real" applications can be developed.
