Institute of Quantum Technologies

Core Departments

Quantum Metrology

The focus of this department is on the development of space compatible quantum metrological instruments, especially with regard to their necessary compactness, reliability and robustness. In order to achieve high measurement accuracies, laser measurement technologies are applied, for example for the realisation of iodine- and resonator-based frequency references, optical frequency combs and laser interferometers. The instruments are used for example in earth observation, navigation or scientific missions.

Quantum Information and Communication

This department investigates topics from the field of quantum information, both, on a fundamental level as well as for technological applications in collaboration with industry. In addition to the realisation of quantum cryptography and worldwide quantum communication, for example on satellites, it is studied how to efficiently communicate over large distances at high loss rates.

Quantum Nanophysics

This department tests the validity of quantum mechanics for high-mass particles by performing matter-wave experiments with nanoparticles like complex molecules or clusters. Beside the realisation of matter-wave interferometers at nanoscale which can be used for tests of new physics, the department explores schemes to prepare the quantum state of nanoparticles. Thus, it develops quantum enhanced sensors with significantly increased sensitivities.

Quantum Control of Charged Matter waves

In this department it is studied how the motion of – free as well as bounded – electrons can be efficiently controlled in order to produce new electron based instruments and devices. More specifically, this research aims for increasing the resolution of electron microscopes with the help of quantum effects, gaining insights into ultrafast processes with electron-light interaction, or miniaturizing electron accelerators down to chip size.

Cross-Sectional Departments

Quantum Engineering

The department works on applicable quantum technologies, which are developed via simulation, design to realisation and testing for the application in space missions but also in the terrestrial area. One goal is the "compacting" of systems and components. To achieve this goal, it is necessary to master individual manufacturing processes and methods, such as assembly- and integration or vacuum technologies, in particular for space applications.

Integration of Micro- and Nanosystems

Focused on the system concept this department provides technologies that operate reliably under adverse conditions. For the functionality of the system, first technological boundary conditions for the requirements are defined. Then solution strategies are developed to overcome these obstacles.

Theoretical Quantum Physics

This department studies and models quantum systems used in quantum technologies. Prominent research fields are atom or matter-wave interferometry, degenerate quantum gases like Bose-Einstein condensates (BECs) in microgravity, or fundamental topics like relativistic effects in quantum mechanics.
