PhD positions in Experimental and Theoretical Quantum Science

position expired
Department of Physics and Astronomy, Aarhus University Denmark DK

The Center for Complex Quantum Systems at the Department of Physics and Astronomy, Aarhus University, invites applications for several PhD positions with exciting opportunities to join new collaborative research projects in theoretical and experimental quantum physics.

Job description/research project/research area

The newly founded Center for Complex Quantum Systems offers a vivid research environment at the exciting interface of quantum optics, quantum information science and many-body physics. Our research focusses on new hybrid quantum systems composed of interacting atoms, ions and photons, and seeks to deepen our understanding of collective quantum phenomena, and to facilitate the development of future applications by developing new techniques to control the dynamics of such quantum systems. Close links to other major research activities, like the ‘Semper Ardens’ research project QCooL (, and the European research networks SQUARE (, C’MonQSens

( and ErBeStA ( provide further opportunities to contribute to collaborative research efforts on quantum nonlinear optics, quantum computing, quantum communication, and quantum sensing. Specific research topics for the open positions include

  • Quantum control of many-body systems subject to continuous probing, measurements and feedback,
  • Quantum sensing and quantum information protocols based on continuous measurements,
  • Light-matter interactions in atomic and solid-state systems and collective phenomena,
  • Theory and implementations of quantum simulations,
  • Mobile impurities and quasiparticles in hybrid quantum systems,
  • New quantum phases of matter, strong correlations and topological order,
  • Quantum dynamics in hybrid systems of ultracold ions and neutral atoms,
  • Collective coupling and quantum-state control of trapped ions in optical cavities,
  • Correlations and quantum effects in Bose Einstein condensates,
  • Optical control of quantum impurities and interacting polaritons in synthetic quantum systems.

Many of these questions will be addressed in both theory and experiment, and the successful candidate will get the opportunity to support and stimulate close collaborations between the experimental and theoretical groups within the CCQ. For more information on specific research directions please contact the participating PI's:

  • Thomas Pohl (
  • Jan Arlt (
  • Georg Bruun (
  • Michael Drewsen (
  • Klaus Mølmer (

Applicants should hold a Masters degree in physics. We are looking for talented and highly motivated applicants with a keen interest in experimental and theoretical AMO physics, quantum information science and technology, quantum optics or statistical and many-body physics. The successful applicants should demonstrate both collaborative skills and an ability for independent original research. The CCQ is aware of the under representation of minorities in physics, and will be happy to welcome and set up the means to mentor a diverse group of researchers who pursue early stage research with us.

The CCQ has been recently founded within the Center of Excellence framework of the Danish National Research Foundation and offers a lively platform for interactions across topics and departments in the broad area of quantum science. The Center wishes to provide optimal conditions for the personal and scientific development of its PhD students, and the successful applicants are encouraged to participate in a variety of transferable skill courses, workshops and programs, offered by Aarhus University. Denmark is known for a high quality of life and a healthy work-life balance, and the city of Aarhus offers many recreational and cultural activities in a safe, tolerant and casual atmosphere.

The positions are available from November 1, 2020
