In the research group "Quantum Logic Spectroscopy" we deal with precision spectroscopy of trapped and laser-cooled atomic ions. Therefore, we develop quantum computer-inspired techniques for the coherent manipulation of ions and their spectroscopy for applications such as high-precision optical atomic clocks.

Your tasks:

  • Development of compact optical setups with automated optimisation of operating parameters

  • Integration of the resulting hardware in a transportable Al+ quantum logic clock

  • Participation in the automation of the clock for continuous operation and characterisation of the clock

  • Participation in in-field measurement campaigns outside the laboratory environment for relativistic geodesy

The post is initially limited to three years; an extension of the contract is possible. You will be employed at our
Hannover site in the brand-new HITec lab building. The remuneration will be paid in accordance with remuneration group 13 TVöD Bund (85 %).

We offer:

  • An excellent research environment (DQ-mat CRC 1227, Excellence Cluster 2123) with access to PTB's unique infrastructure [TODO!]
  • Practical training in modern experimental techniques in laser and quantum physics and active participation in the development of experiments at the forefront of quantum physics research.
  • Possibility to present scientific results at international conferences
  • We encourage research stays abroad with our international collaborators
