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

Oriol Romero-Isart’s research group studies topics in the fields of theoeretical quantum optics, atomic physics, nanophysics, and superconductivity in the context of quantum science: quantum information processing, quantum simulation, quantum metrology, and foundations of quantum mechanics. The researchers focus on proposing cutting-edge experiments and developing the underlying theory while closely collaborating with experimental groups.

Currently, the group is interested in harnessing quantum systems with superconductivity and magnetism to access an unprecedented parameter regime in the fields of quantum nano- and micro-mechanical oscillators, quantum simulation with ultracold atoms, and solid-state quantum information processing.

Quantum Optics and Information

Wittgenstein awardee Peter Zoller’s research group studies topics in the fields of theoretical quantum optics and atomic physics as well as quantum information and condensed matter theory. The researchers mainly focus on theoretically describing real physical systems while closely collaborating with the experimental field and connecting the fields mentioned above in an interdisciplinary approach.

Their main research activities aim to realize, simulate and investigate novel quantum many-body systems consisting of atoms, ions or molecules or based on hybrid systems of optomechanical and solid state systems. In addition, the researchers are developing and searching for new tools and protocols for applications in the fields of quantum information and communication technology.

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.
