The projects explore the coherent control of Andreev bound states that form when semiconducting quantum dots are contacted by several superconducting leads. For spin-ful states, spin-orbit coupling can lead to spin splittings that depend on the superconducting phase bias, rather than the Zeeman field that is typically used to control purely semiconducting spin qubits. The resulting coupling between spin states and supercurrents will allow new ways of coherently manipulating quantum states and opportunities to couple distant spins via supercurrents.

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.
