PhD fellowships

The projects explore the operation of few-qubit arrays using sophisticated control and readout techniques, focusing on semiconducting spin qubits based on silicon and germanium heterostructures that are in some cases made in house and in some cases supplied by research collaborations. On the materials side, isotopic purification of 28Si gives rise to exceptionally long coherence times for electron spin qubits, while strong spin-orbit coupling in the valence band of Ge allows novel hole spin control techniques that are fast and energy efficient. Furthermore, spin-qubit control in high-bandwidth dilution refrigerators by FPGA-powered control electronics allows you to harness recent advances in low-latency signal generation, machine-learning-enabled data acquisition, and real-time quantum control.
The projects combine nanofabrication, low-temperature physics using dilution refrigerators, low-noise and high-frequency electrical measurement and control techniques, data analysis, interaction with theoretical physicists, and scientific writing in English. An active collaboration between experiment and theory in various research groups across Europe is envisioned.
