Postdoc position in Gate-Tuneable Superconducting Quantum Electronics

We, the 202Q-lab, are looking for a highly motivated post-doctoral researcher (“post-doc”) to work on microwave measurements of gate-tuneable superconducting devices. The work will be part of the Horizon 2020 FET Open project SuperGate. This position is immediately available, and we will be continuously evaluating applications. All applications filled in by May 1, 2021 will receive full consideration.

The project
In the last few years, a series of experiments have shown that superconductivity in a weak link can be controlled by applying voltages to electrostatic gates, in a similar way as semiconducting transistors are controlled by the field effect. This discovery has the potential to revolutionize the world of supercomputing, leading to a technology that would combine the advantages offered by semiconductors and superconductors. However, the underlying physical mechanism behind it is still unclear. In addition, the control has been demonstrated only at low frequencies (dc and audio band), while many prospected applications require switching at much higher frequencies (GHz and above).

Job description / Responsibilities
The successful candidate will integrate gated weak links into superconducting radiofrequency and microwave circuits to be cooled down to temperatures between 10mK and 4K. The candidate will perform high-frequency measurements to shed new light on the microscopic origin of the gating effect, and to optimize its speed and performance in view of integration into more complex logic circuits. In addition, the candidate will be encouraged to contribute to the conception and proof-of-principle demonstration of novel microwave devices based on this effect. To succeed, the candidate will leverage our in-house expertise in nanofabrication and state-of-the-art microwave measurements in time and frequency domain, as well as the diverse and complementary knowledge available in the SuperGate consortium, from transport measurements, to material science, to system integration.

The candidate may be responsible for:
• concept, circuit design and physical design of microwave superconducting circuits
• device fabrication using e-beam lithography and subtractive processes
• microwave and time-domain characterization measurements

Qualifications
You hold a PhD degree in areas such as: Physics, Engineering/Applied Physics, Microtechnology, Microwave Engineering. The degree should generally not be older than three years. Ideally, you have hands-on experience in at least some of the following: mesoscopic physics, quantum physics, nanofabrication, cryogenics, microwave design, microwave measurements. You see yourself as pursuing a career in research & development or education, either in the academia or in the industry. You are driven by scientific curiosity and by a desire to make a difference. You can confidently read, write, and discuss science in English. We will consider outstanding candidates with proven track record in any field of physics or engineering.

Position summary
Full-time temporary employment. The duration of the project is three years. The initial contract will be made for one or two years.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.

Our division
At the Quantum Technology division of the Microtechnology and Nanoscience department, we pursue state-of-the art research in quantum information science, microwave quantum optics, and mechanical quantum devices. We are also part of the Wallenberg Centre for Quantum Technology (WACQT), a 12-year initiative, started in 2018, for the purpose of advancing Swedish academia and industry to the forefront of quantum technology, and to build a Swedish quantum computer.
