28.02.2016 - 16:54 article in the „Physik in unserer Zeit“

A recent open-access article by research partners from the BMBF Research Network project entitled "Sichere Kommunikation per Quantenrepeater" is published in "Physik in unserer Zeit", which reports on the current state and the main challenges in this field.




The department "Technische Physik" is engaged in the fabrication and characterization of nanostructured materials and their applications in novel devices. A major focus lies on semiconductor nanostructures and optoelectronic as well as nano-photonic devices, which are dedicated for classical optical communication as well as for quantum information processing or communication.

Research Groups

The department is divided in four research groups. Each of them is focussed on a specific research topic.
