Measuring quantum devices at temperatures near absolute zero

The mission of the newly founded Institute for Functional Quantum Systems (PGI-13) is to create the technological and scientific basis to enable useful quantum computing. We focus on developing quantum devices, improving their coherence and materials, and implementing quantum gates and algorithms. We use superconducting qubits that operate at temperatures close to absolute zero and are controlled by high-speed signals. A key requirement is to preserve high quality quantum operations as we scale. Overcoming these exciting challenges lies at the interface between scientific research and engineering.

We are looking to recruit a

PhD-Position - Development of scalable superconducting quantum systems

Your Job:

This position focuses on building, operating, and testing superconducting quantum devices. Your tasks in detail are:

  • Design and fabrication of superconducting quantum circuits
  • Setting up experimental systems for cryogenic measurements
  • Development of a microwave quantum control & readout stack
  • Development of Python code to operate quantum systems
  • Detailed experimental characterization of superconducting qubits to quantify performance and identify limiting physical mechanisms
  • Perform quantum device calibrations, benchmarking, and run quantum algorithms
  • Presenting and publishing the research on an international stage

Your Profile:

  • Master in physics or electrical engineering
  • Knowledge of solid state physics and/or quantum information
  • Experience with programming, preferably with Python
  • Fluent speaking and writing skills in English
  • Team-oriented and highly motivated to work in an experimental laboratory
  • A background in quantum computing as well as experience with cryogenics, signal delivery, microfabrication, materials optimization, and microwave control are highly preferred qualifications

Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We offer optimal conditions for you to perform your doctoral research:

  • A highly motivated team as well as an international and interdisciplinary working environment at one of Europe’s largest research establishments
  • State-of-the-art scientific and technical infrastructure
  • Continuous scientific mentoring by your advisor
  • A large research campus with green spaces, offering the best possible means for networking with colleagues and pursuing sports alongside work
  • Participating in international conferences and workshops
  • Opportunity to take part in enabling useful quantum computing
  • Further development of your personal strengths, e.g. through an extensive range of training courses; a structured program of continuing education and networking opportunities specifically for doctoral researchers via JuDocS, the Jülich Center for Doctoral Researchers and Supervisors: https://www.fz-juelich.de/judocs
  • Targeted services for international employees, e.g. through our International Advisory Service


The position is initially for a fixed term of 3,5 years; extensible to 4 years. Pay in line with 75% of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund) and additionally 60 % of a monthly salary as special payment („Christmas bonus“). Further information on doctoral degrees at Forschungszentrum Jülich including our other locations is available at: www.fz-juelich.de/gp/Careers_Docs

Forschungszentrum Jülich promotes equal opportunities and diversity in its employment relations. We also welcome applications from disabled persons.

To apply, please submit a complete CV, letter of motivation, university degree records (both Bachelor’s and Master’s degree), as well as two reference letters.
