PhD Position – Development Of Scalable Superconducting Quantum Systems

The mission of the Institute for Functional Quantum Systems (PGI-13) is to create the technological scientific basis to make quantum computing usable. We focus on developing quantum devices, improving their coherence and materials, and implementing quantum gates, algorithms, and architectures. 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.

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

As part of our experimental team, you will regularly work in state-of-the-art laboratories and clean rooms. The role involves working in a cryogenic laboratory environment and following specific clean room protocols

• Master’s degree in physics or electrical engineering or a related field
• Willingness to work in laboratory and cleanroom environments
• Ideally, initial experience in a technical or scientific environment (e.g. cleanroom, laboratory)
• Knowledge of solid state physics and/or quantum information
• Experience with programming, preferably with Python
• Fluent written and spoken English (at least C1 level according to the CEFR), ideally supported by a certificate confirming the language level
• 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

Please feel free to apply for the position even if you do not have all the required skills and knowledge. We may be able to teach you missing skills during your induction.

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 support you in your work with:

• Team & Environment: You will work in a motivated team with an international and interdisciplinary focus – at one of the largest research institutions in Europe
• Research & Infrastructure: You will have access to excellent scientific and technical facilities for your work
• Supervision & Support: We will accompany your doctoral studies with continuous, expert guidance from your academic supervisor
• Work-life balance: We offer flexible working hours to help you balance your professional and personal life. You also have the option of flexible working (in terms of location), which is generally possible after consultation and in line with upcoming tasks and (on-site) appointments
• Annual Leave: You get 30 days of annual leave
• Health & well-being: Your health is important to us. You can look forward to a comprehensive company health management programme with a wide range of options, including a beach volleyball court, running groups, yoga classes and much more. In addition, our company medical service and an experienced social counselling team are available to assist you on site
• Campus experience: Our research campus in the countryside creates ideal conditions for collegial exchange and sporting activities right on site. Our cafeteria offers a wide range of options—you can enjoy a relaxing lunch break with a lake view
• Fair remuneration: Depending on your qualifications and assigned responsibilities, you will be classified according to pay group 13 (75%) of the TVöD-Bund. In addition to the basic salary, there is an additional year-end bonus under the collective pay agreement amounting to 75% of a monthly salary, as well as capital-forming benefits. All information about the TVöD-Bund collective agreement can be found on the BMI website (pay scale table on page 66 ff. of the PDF download)
• Perspective: The position is initially for a fixed term of 3.5 years but with the prospect of longer-term employment
• Support for international employees: Our International Advisory Service makes it easier for international employees to get started

In addition to exciting tasks and a collegial working environment, we offer you much more: https://go.fzj.de/benefits
