Interested in a Masters or PhD project?
Highly motivated students are currently being sought. Group projects involve:
- Design, fabrication and experimental characterization of semiconductor quantum devices
- Quantum transport at cryogenic temperatures
- Theory, simulation and modeling
- Scalable QC architectures based on spin qubits
Students will gain both hands-on and theoretical experience across Physics, Chemistry, Materials Science and Electrical Engineering. Firm theoretical grounding (especially quantum mechanics), strong experimental aptitude and creativity are key qualities.
