Quantum Optics

In the area of quantum optics, there are three research groups at our institute concentrating on different questions and priorities:

 

Cavity Quantum Electrodynamics

The research group of Helmut Ritsch covers the fields of theoretical quantum optics and ultra cold gas physics with strong connections to quantum information theory, foundations of quantum physics and quantum theory of condensed matter systems. We focus on full quantum descriptions of matter and light waves, which are strongly coupled by momentum exchange.

Our aim is an effective theoretical description of real physical systems in a close connection with experiments, where genuine quantum phenomena as quantum phase transitions, entanglement and macroscopic super positions can be studied in a well-controlled and understood environment.

Quantum Nanophysics, Optics and Information

The research group led by Oriol Romero-Isart studies topics in the fields of theoretical quantum optics and quantum nanophysics in the context of quantum science and technology. One of the main research interests is the observation of quantum phenomena with levitated micrometer-sized particles. Such systems push the boundary of quantum physics into uncharted territory, where the very validity of quantum physics and its interplay with gravity could be put to the test.

Achieving this goal requires a fundamental understanding of the internal physics of levitated nanoparticles as well as their interaction with electromagnetic fields. The group is also interested in nano-optics, including topics such as the tailoring of spatio-temporal features of the electromagnetic field, light-matter interaction at the nanoscale, and out-of-equilibrium quantum electrodynamics.  The group proposes cutting-edge experiments and develops the underlying theory while closely collaborating with experimental groups.

Quantum Optimization

The research group of Wolfgang Lechner is dedicated to theoretical quantum physics with the aim to solve computationally challenging problems efficiently in near term quantum devices. The focus is research of coherent adiabatic and non-adiabatic processes, applications in machine learning and optimization problems as well as the investigation of implementations in different next generation qubit platforms.
