Open positions within ML4Q are listed here (this page is updated regularly). Since most research group within ML4Q hire PhDs and post-docs individually, it might be advisable for potential candidates to contact suitable ML4Q members directly. Please note that there are no cluster-wide application deadlines for positions within ML4Q.

(Assistant) Professorship in Experimental Condensed Matter Physics (W2 / W1 with tenure track to W2) (f/m/x)

We are looking for an internationally recognized experimental researcher working on the control and/or exploration of quantum materials, with a clear potential for collaboration within the Collaborative Research Centre “Control and Dynamics of Quantum Materials“, CRC 1238. Experimental methods may be laboratory-based
and/or rely on large-scale research facilities such as synchrotron or neutron sources. Qualification requirements include an excellent track record in research. Excellence in teaching and successful 3rd party funding acquisition are expected for W2 applicants and are desirable for W1 applicants. [link to full job description]

Student assistant position at Fraunhofer FHR in cryogenic engineering

ML4Q partners at Fraunhofer FHR in Wachtberg near Bonn are looking for students to assist on ongoing work in cryogenic engineering. The position offers a good opportunity to get some practical experience in cryogenic –  combined with microwave –  engineering.
More details in the job description [only in German].

Any questions? Drop Andreas Fröhlich a line (andreas.froehlich(at) or give him a call (+49 228 9435-769)

The position is also available for English speaking students. Here are the most important infos:

In the context of quantum technologies, an automated cryogenic measuring station for high-frequency measurement technology up to 67 GHz is to be set up at FHR. For this purpose, the cryogenic systems will be centrally controlled, sensors for pressure, temperature, etc. will be read out and high-frequency measurements for characterization will be automatically triggered, and a control system will be implemented to set the cryogenic systems to a stable temperature between 4 and 300 Kelvin.

Your task

  • After familiarizing yourself with the functionality of the cryogenic high-frequency measurement systems, your task will be to create an automated control system for the plant. You will have the opportunity to deal with exciting topics such as 4-Kelvin and high-frequency systems up to 67 GHz. This includes mechanical design, thermodynamic aspects and vacuum technology, as well as high-frequency measurement technology using network and spectrum analyzers, etc.
  • Implementation of the automated measuring station using Python
  • Integration of a Siemens Logo!8 SPS in Python
  • Setting up a control loop to control specific temperatures between 4 and 300 Kelvin


  • Current enrollment in physics, electrical engineering or mechanical engineering
  • Thermodynamic understanding
  • Interest or initial knowledge in mechanical and high-frequency measurement technology (e.g. network analyzers, spectrum analyzers, etc.)
  • Initial experience in control and automation technology
  • Initial experience in the programming language Python and Siemens LOGO of advantage

Your benefits

  • Prospect of a final thesis
  • Interesting, practical tasks
  • Insights into current research projects from industry and basic research
  • Open and collegial working environment with relaxed interaction and modern equipment
  • Attractive conditions at one of the largest research organizations for application-oriented research in Europe
  • Excellent networking within the international research landscape

Remuneration is based on the general works agreement on the employment of auxiliary staff. The position is initially limited to a period of 6 months. The maximum weekly working time for student assistants is 19.5 hours. Individual part-time agreements are possible.
