Type of employment


"Cutting-edge research requires excellent minds – particularly more females – at all levels. Launch your mission with us and send in your application now!" Prof. Pascale Ehrenfreund - Chair of the DLR Executive Board

The Institute of Optical Sensor Systems investigates and develops active and passive optical sensor systems for satellites, flying platforms and robotic systems. The institute is participating in the scientific analysis of the resulting data. It is involved in numerous national and international cooperations.

Photonic quantum memories are so far missing key components for the second quantum revolution and enable a plethora of novel applications. For example, quantum networks promise not only physical instead of algorithmic security in communication but also the possibility for connecting quantum computers and simulators for calculations and simulations on distributed machines.

The recently founded Group on Physical Foundations of IT-Security focuses on the one hand on the development of non-classical light sources and quantum memories for single photons. On the other hand, security-relevant applications of these key components in the emerging quantum technologies are explored. Most prominent, quantum secured communication and optical computation in the quantum and classical regime are in the research focus.

At the beginning of the PhD work, a quantum memory for single photons in alkaline vapor at room temperature is built and optimized with respect to noise, efficiency, bandwidth and storage time. Special remark is on the suitability of the used components for future airborne and space missions. Later, the memory is tested in first applications.

To support our dynamic team, we are looking for a highly motivated student with first experiences in experimental quantum optics or atomic physics to realize a quantum memory experiment and to develop tools and methods for optimizing the memory.

Please send a letter of motivation summarizing your qualification and academic interests, a complete CV and transcription of grades/diplomas. Letters of recommendation from previous supervisors and mentors will be considered. In case of questions, contact

Your working time will be 19,25 hours per week.

Your qualifications:
