PhD position: Strained Germanium Quantum-Well Transistors for Integrated Cryogenic Spin Qubit Readout (P2607) University of Basel in Switzerland

University of Basel is offering a PhD position on strained Germanium quantum-well transistors for integrated cryogenic spin qubit readout (P2607). The project sits at the intersection of quantum computing, condensed matter physics, cryogenic device physics, and semiconductor nanoelectronics, with a strong emphasis on scalable hardware for future quantum processors.

Hole-spin qubits in planar germanium quantum wells are attractive because they combine fast electrical control, compact device geometry, and strong performance in a semiconductor platform. A key challenge for scaling these systems is readout: qubit states must be transformed into small electrical signals and detected quickly and reliably. This PhD project explores Ge/SiGe quantum-well transistors as integrated cryogenic readout devices, aiming to move amplification and signal routing closer to the quantum device and thereby reduce reliance on external wiring and room-temperature electronics.

The research combines advanced material growth, nanoscale fabrication, and cryogenic transport/device measurements within a single platform. Successful work could contribute to more compact and scalable readout architectures and strengthen planar germanium as a platform for integrated quantum nanoelectronics and large-scale semiconductor quantum computing.

The position is hosted at the University of Basel in Switzerland and includes membership in the Swiss Nanoscience Institute (SNI) PhD school, described as a supportive and recognized community with about 30 currently supported scientists. The SNI environment spans quantum physics, chemistry, materials science, nanotechnology, biochemistry, cell biology, and medical research.

Eligibility: candidates should hold a Master’s degree in nanoscience, physics, or a related engineering discipline. Experience with fabrication or transport measurements is welcome but not mandatory.

Funding and conditions: the advertisement highlights very competitive employment conditions and participation in the SNI PhD school. The post is a funded doctoral employment opportunity rather than a scholarship-only award.

Application: more information and the online application platform are available via www.phd.nanoscience.ch and the linked application page. Questions may be directed to Dr. Andreas Baumgartner at [email protected] or to the project leaders. The application should be completed by 15 October 2026, with a note that the vacancy may be filled any time from now; the broader text also mentions completion before 31 December 2026.
