Research groups

Theoretical quantum optics (Hammerer group)

The focus of the group lies on the control of optical, atomic and nanostructured quantum systems.
Research goals are:

  • quantum-limited control of physical systems for the implementation of protocols for quantum information, quantum communication and quantum metrology
  • Advance quantum effects in mesoscopical and macroscopical systems in order to fathom the transition from the quantum to the classical regime.

Quantum Transport in Semiconducting Nanostructures (Haug group)

The group investigates quantum effects in semiconductor nanosctructures by means of
magneto-transport experiments.
Beside pure transport measurements the focus also lies
on electronic noise and counting statistics applied to e.g. tunneling processes through quantum dots.

Quantum control (Heurs/Danzmann group)

The group is concerned with the control of complex systems, which exhibit noise at or below the quantum level, by means of classical and modern control, such as

  • Laser frequency and power stabilization
  • Control of squeezed light sources
  • Generation of GHz-squeezed light combs

Quantum gases and ultra-cold molecules (Ospelkaus group)

The research group, located at the institute for quantum optics, investigates the properties of ultra cold atomic and molecular gases. Thereby the focus lies on the analysis and realization of dipolar complex quantum many body systems in quantum gases of ultra cold polar molecules.
