Are you excited about pioneering experimental quantum computing? Do you want to be part of a world-class research environment developing the next generation of superconducting quantum processors?
We are seeking a Postdoctoral researcher to join our ambitious team at the Wallenberg Centre for Quantum Technology (WACQT), based at the Department of Microtechnology and Nanoscience (MC2).
About us
The Department of Microtechnology and Nanoscience (MC2) advances the frontiers in quantum technology, nanoscience, photonics, and future electronic systems. Our cross-disciplinary approach drives innovations through collaborations across academia, industry, and society. We offer a vibrant, international environment with direct access to world-class nanofabrication facilities.
At the Quantum Technology Laboratory (QTL), we explore how quantum physics can unlock radically new ways of processing information. Our research spans quantum computing, sensing, transduction, and thermodynamics, aimed at harnessing the behavior of light and matter at the quantum level.
About the research project
This project is a proof-of-concept effort aimed at demonstrating a reliable post-fabrication trimming process for Josephson junctions in superconducting qubits.
Unlike open-ended exploratory research, this project is goal-oriented and experimentally driven. It requires both careful physical interpretation and structured technical validation. You will take primary responsibility for planning and executing the experimental program in collaboration with senior researchers. While the role does not include formal personnel management, scientific initiative and independence are highly expected.
Key responsibilities include:
- Designing and executing cryogenic experiments.
- Characterizing Josephson junctions and superconducting circuits.
- Analyzing device behavior and degradation mechanisms.
- Correlating electrical performance with material properties (aging, interfaces, coherence).
- Contributing to reproducible superconducting qubit fabrication workflows within WACQT.
The project is closely connected to ongoing superconducting quantum processor development efforts within WACQT.
Who we are looking for
The following requirements are mandatory:
- A PhD in Physics, Applied Physics, Materials Science, Electrical Engineering, or a closely related field.
- Strong experimental research experience in superconducting devices, quantum devices, low-temperature physics, nanoscience, or related areas.
- Experience with at least one of the following:
- programming experience in Python
- MATLAB
- or similar tools for data analysis and experiment automation.
You are expected to be somewhat accustomed to teaching, and to demonstrate good potential within research and education.
The following experiences are considered beneficial, but are not required:
- Dilution refrigerator operation.
- Transmon qubit measurements.
- Microwave control and readout.
- Quantum coherence measurements.
- Thin-film characterization.
- Tunnel junction fabrication.
- Cleanroom micro/nanofabrication.
- Device simulation or modeling.
We recognize that strong candidates may not match every listed qualification. If your experience aligns with part of the profile and you are interested in the project, we encourage you to apply.
What you will do
Experimental research
- Design and execute experiments on superconducting quantum devices.
- Develop and validate electrical trimming methods for Josephson junctions.
- Perform low-temperature measurements using dilution refrigerators.
Device characterization and analysis
- Characterize superconducting circuits using DC, AC, and RF measurement techniques.
- Analyze complex experimental datasets and develop physical interpretations of device behavior.
- Investigate relationships between fabrication processes, material properties, and device performance.
Collaboration and scientific communication
- Work closely with researchers in superconducting qubit development, nanofabrication, and materials characterization.
- Present results internally and externally through publications, reports, and conference presentations.
The position is meritorious for future roles in academia, industry, or the public sector.
Contract terms
The position is a temporary full-time employment for two years with the possibility of a one-year extension.
The position requires physical presence throughout the entire employment. A valid residence permit must be presented by the start date, otherwise the offer may be withdrawn.
