Résumé/Abstract : Recent years superconductor-semiconductor hybrid materials have been established as an essential platform for quantum devices, notably used in the search for novel bound states that may serve as qubits. In this talk we firstly focus on the excitations and correlations arising in short chains of coupled quantum dots and superconducting islands. We then take a look beneath the surface of these nanowire devices, addressing advances in materials science where in situ MBE fabrication and various superconductors have been implemented in order to expand the available parameter space for hybrid devices.
