## Description

- description: "The observation of Josephson current in the quantum Hall regime has
    attracted considerable attention, revealing the coexistence of two seemingly incompatible
    phases: the quantum Hall and superconducting states. However, the mechanism underlying
    the Josephson current remains unclear because of the observed ℎ⁡/2⁢\U0001D452
    magnetic interference period and the absence of precisely quantized Hall plateaus.
    To address this issue, we investigate the edge dependence of the Josephson current
    in graphene Josephson junctions operating in the quantum Hall regime. By systematically
    comparing devices with native, etched, edge-free, and gate-defined edges, we demonstrate
    that the Josephson current is confined to the physical edges and is highly sensitive
    to specific edge configurations. Our findings provide direct evidence that counter-propagating
    quantum Hall edge states mediate Andreev bound states, enabling Josephson coupling.
    These results clarify the underlying mechanism of Josephson current in the quantum
    Hall regime and offer new strategies for engineering superconducting hybrid devices."
