Lund University – Faculty of Engineering (LTH), Division of Solid-State Physics, Department of Physics is seeking a Postdoctoral Researcher to contribute to the QPHOTON project, focused on developing high-efficiency microwave photon detectors for quantum technology. Embedded within the renowned NanoLund research center, this position provides access to leading nanoscience facilities, including Lund Nano Lab, and a strong interdisciplinary environment spanning materials science, nanotechnology, semiconductor physics, and quantum research.

The postdoctoral researcher will work within Ville Maisi’s research group, exploring the quantum mechanical measurement processes that occur in photodetectors designed to count microwave photons with minimal backaction. The role focuses on advancing experimental understanding of coupled microwave resonator–semiconductor quantum dot systems, enabling progress in quantum sensing and measurement technologies.

Key responsibilities:

• Conduct experiments probing photonic and electronic responses in hybrid microwave–semiconductor nanostructures.

• Investigate quantum measurement backaction and detector efficiency through controlled variation of system parameters.

• Contribute to device fabrication through cleanroom processing and participate in the development of measurement setups.

• Collaborate with theory groups and supervise PhD students, contributing to publications and group research activities.

• Teaching or departmental duties may be included up to 20%, extending the contract duration accordingly.

Required qualifications:

• PhD (or equivalent) in a field relevant to semiconductor quantum devices, solid-state physics, quantum technology, or experimental physics.

• Excellent written and spoken English.

• Strong research capability with experience in experimental physics.

Merits:

• Expertise in low-temperature transport, high-frequency measurements, or experimental quantum devices.

• Experience with cleanroom nanofabrication, and programming for data acquisition/analysis (e.g., Python or Matlab).

• Demonstrated ability to conduct independent research and contribute to collaborative efforts.

This full-time postdoctoral appointment is two years, offering an excellent opportunity to advance your research independence within a world-class nanotechnology and quantum research environment.
