Post-doctoral researcher: Control of germanium spin qubits based on shuttling between squeezed quantum dots and on geometric effects (M/F)

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description Germanium heterostructures are an emerging platform for spin-based quantum technologies as they combine long coherence times with strong spin-orbit interaction. Spin qubit arrays in germanium therefore offer new opportunities for quantum information processing, as well as for the exploration of fundamental quantum phenomena. This project aims to implement state-of-the-art spin qubit experiments in two-dimensional germanium quantum dot arrays. More precisely, it aims to investigate new spin manipulation techniques based on geometric quantum effects and on coherent spin shuttling. The candidate will participate to one of the following projects:. • Exploration of non-Abelian geometric phases generated by single-spin motion at zero magnetic field. • Investigation non-resonant geometric driving of hole spin qubits. • Study of hopping-based operations in arrays of squeezed quantum dots. The candidate's activities will include:. • Helping to develop the cryogenic setup dedicated to the aforementioned experiments and, in particular, working on the RF and DC wiring. • Designing and fabricating the germanium quantum dot arrays. • Tuning and controlling the charge filling of the arrays. • Performing single-spin manipulation and transport experiments. • Analysing the results of the experiments in collaboration with experts in the modelling of hole spin qubits in germanium. • Training and mentor
