## Description

- description: 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 states1,2,3,4,5,6.
    This interest has been motivated by prospects of finding new physics, including
    topologically protected quasiparticles7,8,9, but also extends into metrology and
    device applications10,11,12,13. So far it has proven challenging to achieve detectable
    supercurrents through quantum Hall conductors2,3,6. Here we show that domain walls
    in minimally twisted bilayer graphene14,15,16,17,18 support exceptionally robust
    proximity superconductivity in the quantum Hall regime, allowing Josephson junctions
    to operate in fields close to the upper critical field of superconducting electrodes.
    The critical current is found to be non-oscillatory and practically unchanging
    over the entire range of quantizing fields, with its value being limited by the
    quantum conductance of ballistic, strictly one-dimensional, electronic channels
    residing within the domain walls. The system described is unique in its ability
    to support Andreev bound states at quantizing fields and offers many interesting
    directions for further exploration.
