Quantum Optics Theory

The development of laser cooling and trapping techniques for atoms enabled us for the first time to study and fully control individual quantum systems in the lab. Apart from progressively  refined tests of the laws of quantum mechanics these capabilities also provide us with the basis  for new, quantum-enabled technologies, such as quantum computers, quantum simulators or enhanced sensors.  In recent years a similar level of control has also be obtained for artificial and macroscopic quantum systems, like superconducting quantum circuits or nanomechanical resonators. 

In our research group we are interested in quantum optical phenomena at the crossover between the microscopic and the macroscopic world and potential applications of coherent solid state and hybrid quantum systems for future quantum technologies.


Current research topics:

• Ultra-strong coupling effects in multi-qubit circuit QED. 

• Defect-phonon interactions and phonon quantum networks in diamond. 

• PT-symmetry breaking and exceptional point phenomena in nanomechanical and other microscopic quantum systems.

• Strong-coupling phenomena and multi-photon bound states in waveguide QED.

• Preparation and verification of macroscopic quantum superpositions.
