Wallenberg postdoc position: Qubit decoherence

We are looking for a motivated postdoc who is interested in decoherence of superconducting qubits. In collaboration with a Canadian group and SnoLAB in Canada we will investigate correlated errors in qubits caused by cosmic radiation and radioactivity. Measurements will be made both at ground level and 2 km underground in SnoLAB. The aim of this project is to understand qubit errors from ionizing radiation and to find ways to avoid and reduce such errors.

Information about the research program
The Wallenberg Centre for Quantum Technology (WACQT) is a 12-year, SEK 1 billion research program that started in 2018 and aims to take Swedish research and industry to the forefront of quantum technology. Our main project is to develop a high-end quantum computer based on superconducting qubits. WACQT is directed and coordinated from Chalmers University of Technology, however several Swedish universities are involved. The research areas quantum sensing and quantum communication are coordinated from Lund University and KTH Royal Institute of Technology, respectively. WACQT also has several industrial partner companies, see Industrial collaboration​.

The centre has also started the gender-balance initiative Women in WACQT (WWACQT) that aims at raising awareness on discrimination, and at supporting the career of women and gender non-conforming scientists in the WACQT community. 

Major responsibilities
Your major responsibility as postdoc is to perform microwave measurements at very low temperatures on superconducting circuits. You will do coherence measurements on multiple-qubit samples and look for correlated errors. Measurements will be done both at Chalmers, at Waaterloo and at SnoLab to understand the origin of such correlated errors. An important task would also be to find ways to reduce the correlated errors and/or the impact of them.

As postdoc you would be part of a big group that together strives to build a quantum computer. This particular subproject aims at removing or circumventing a potential road-block towards the main goal. You would work with very advanced technology and be part of a Swedish-Canadian collaboration. Travels to Canada would be part of the work.

Qualifications
To qualify for the position of postdoc, you must have a PhD in physics. Experience with superconducting circuits and microwave measurements is highly desirable. Knowledge of cosmic radiation and radioactivity is also a merit. The position requires sound verbal and written communication skills in English. Swedish is not a requirement, but Chalmers offers Swedish courses.

Contract terms
This postdoc position is a full-time temporary employment for two years.

We offer
Chalmers offers a cultivating and inspiring working environment in the coastal city of Gothenburg.
