Extensive efforts have been undertaken to combine superconductivity and the quantum Hall effect so that Cooper-pair transport between superconducting electrodes in Josephson junctions is mediated by one-dimensional edge states1-6 . This interest has been motivated by prospects of finding new physics, including topologically protected quasiparticles7-9 , but also extends into metrology and device applications10-13 . So far it has proven challenging to achieve detectable supercurrents through quantum Hall conductors2,3,6 ...
