Postdoctoral or PhD for transportable optical ion clocks

The QUEST Institute for Experimental Quantum Metrology is a joint institution of the Leibniz Universität Hannover and the PTB in Braunschweig. 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. The main workplace will be in the brand-new HITec lab building in Hannover

We offer:

• A position at one of the world’s leading research institutions with an excellent infrastructure
• An excellent research environment (DQ-mat CRC 1227, Excellence Cluster 2123) and outstanding national and international networking
• 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.
• We encourage research stays abroad with our international collaborators
• Remuneration in accordance with the collective bargaining agreement for the public service (Tarifvertrag öffentlicher Dienst Bund – TVöD for the federal level)
• Remuneration for PhD students is based on salery group E13 (85%), for Postdocs up to E14.
• Position limited until December 31, 2025
• Good work-life balance (flexible work and part-time models possible)
• Good transport connections (bus and bike); Subsidy for Jobticket Germany; free parking

Your tasks:

• Development and operation of a transportable Al+ quantum logic clock with 10-18 uncertainty
• Development of compact optical setups with automated parameter optimization
• 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
• Presentation of scientific results at national and international conferences

Your profile:

• You have obtained an excellent university degree in physics
• You are interested in developing and realising precision experiments
• Sound knowledge of atomic physics and experience in the field of quantum optics, laser cooling, laser spectroscopy or related subjects is advantageous
• Basic programming skills (e.g. Python)
• Basic skills in electronic engineering
• You are highly committed and capable of working both autonomously and together as part of a team, and you are willing to improve your skills
• You are a team player and have good communication skills
• You have the physical ability to work in a laboratory and to perform experiments outside the institute
