The notion of topological phases has been extended to higher-order and hasbeen generalized to different dimensions. As a paradigm, Cd3As2 is predicted tobe a higher-order topological semimetal, possessing three-dimensional (3D) bulkDirac fermions, two-dimensional (2D) Fermi arcs, and one-dimensional (1D) hingestates. These topological states have different characteristic length scales inelectronic transport, allowing to distinguish their properties when changingsample size. Here, we report an anomalous dimensional reduction of supercurrenttransport by increasing the size of Dirac semimetal Cd3As2-based Josephsonjunctions. An evolution of the supercurrent quantum interferences from astandard Fraunhofer pattern to a superconducting quantum interference device(SQUID)-like one is observed when the junction channel length is increased. TheSQUID-like interference pattern indicates the supercurrent flowing through the1D hinges. The identification of 1D hinge states should be valuable for deeperunderstanding the higher-order topological phase in a 3D Dirac semimetal.
