JARA-Institute for Quantum Information (PGI-11), member of the Peter-Grünberg Institute (PGI), is focusing on theoretical and experimental development of large-scale quantum computing system. Yet, the institute will be the member of the national GEQCOS consortium with its main objective to design, build and operate a quantum information processor based on superconducting quantum circuits reaching the performance necessary for the implementation of Quantum Error Correction.

We are looking to recruit a

PhD Position - Experimental Superconducting quantum computing

Your Job:

Superconducting cubits are considered today as the most real and feasible approaches to the development of multi-qubit quantum computer. Physically, these superconducting qubits are just electrical non-linear circuits nanofabricated by utilizing very thin aluminium film, which becomes superconducting at temperatures below 1 Kelvin. Our work initially aims at the setting up the millikelvin cryogenic system, development of microwave control and readout electronics, preparation of the measurement/data processing software and enabling the remote control of all instruments. We finally aim at the demonstration of the fully-functional, working and accessible multi-qubit quantum processing platform with the-state-the-art performance which will allow for the implementation of Quantum Error Correction algorithms. Yet, with a cooperation involving local research groups we plan to establish reliable fabrication of superconducting quantum circuits in FZ Jülich with the state-of-the-art performance in terms of coherence, gate fidelities and gate errors.

Your tasks in detail are:

  • Experimental investigation and implementation of quantum processing algorithms with superconducting multi-qubit platforms
  • Development and characterisation of superconducting qubits as well as investigations of the underlying decoherence processes
  • Development of microwave quantum control/read-out systems
  • Experimental data processing and their detailed analysis
  • Development of python-software for the remote control of instruments
  • Fabrication of superconducting quantum circuits and their characterisation and optimisation during the fabrication process
  • Presentation, communication, and publication of cutting-edge research in the international community

Your Profile:

  • Excellent University degree in quantum physics or electro engineering
  • Deep knowledge in solid-state physics and/or quantum optics
  • Team-oriented, reliable and highly motivated character
  • Experimental experience at least in one of the fields: Cryogenics, Microwave, Quantum Information processing or Quantum optics
  • Good written and oral communication skills in English

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 ideal conditions for you to complete your doctoral degree:

  • We offer a world-leading, international and interdisciplinary research environment, provided with the state-of-the-art experimental equipment and versatile opportunity for your professional growth as a serious researcher
  • Tight connections to the world leading theory groups in the field of quantum information processing
  • A highly motivated group with connections to the best research institutions across European Union and beyond
  • Chance of participating in local and international conferences and project meetings
  • Continuous, professional support by your scientific supervisor
  • Targeted services for international employees, e.g. through our International Advisory Service


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