Abstract:
The present disclosure relates to semiconductor based Josephson junctions and their applications within the field of quantum computing, in particular a tuneable Josephson junction device has been used to construct a gateable transmon qubit. One embodiment relates to a Josephson junction comprising an elongated hybrid nanostructure comprising superconductor and semiconductor materials and a weak link, wherein the weak link is formed by a semiconductor segment of the elongated hybrid nanostructure wherein the superconductor material has been removed to provide a semiconductor weak link.
