The research area of the department is optical satellite communication for links from low and geostationary orbit to the ground and between satellites. In addition, the department deals with optical aeronautical communication for e.g. passenger aircraft and drones. These mentioned systems can be described by the term classical optical communication. Another important research area is satellite-based quantum communication. Here, the department is working on solutions to efficiently transmit photonic quantum states between satellites and ground stations.

Signal reception and experimental measurement are performed with DLR ground stations in Oberpfaffenhofen. For this purpose, a permanently installed optical ground station (OGS-OP) is available for scientific experiments and measurements, as well as a transportable optical ground station (TOGS) for data reception and technology demonstrations.

Become a part of the research group "Quantum Communication Systems"!

In the field of quantum communication, this group focuses on research on systems for quantum state transmission and corresponding applications using satellites and aircraft. The focus is currently on the socially important area of quantum key distribution, but also on future applications beyond this. The group's activities include the conceptual design of overall satellite-based quantum communication and classical communication systems, the study of specific building blocks such as ground interface or channel characterization, and space- or aircraft-qualified implementations.

The Institute's dedicated optical ground stations allow for appropriate measurement and demonstration campaigns to be conducted to verify the research in the field and to demonstrate the capabilities of the technology.

You will work in the field of quantum communication, especially quantum key distribution, and classical communication. The particular focus of your work will be the systems engineering and further development of the institute's fixed optical ground station (OGS-OP). For the ground station, you will develop systems for high-precision and interference-free transmission of quantum states with a focus on quantum key distribution. The associated modeling of optical systems and subsystems, investigation of the influence of component and system specifications on signal quality, research and investigation of detection systems, and understanding the influence of the atmosphere on signal properties are part of your scope.

We offer you the collaboration on innovative research projects with state-of-the-art technology in an ambitious international environment. Flexible working hours including an individual agreement for mobile working are part of our offer to you.
