| Abstract | Topological semimetal nanowires in proximity with s-wave superconductors are promising for Majorana-based topological quantum computers. To braid the Majorana modes, an interconnected nanowire network coupled to superconductor islands is required. Here, we have fabricated the nanostructures based on two Dirac semimetal Cd3As2 nanowires connected in parallel to form a symmetric superconducting quantum interference device (SQUID). A proximity-induced superconducting state is achieved in the SQUID, and its gate voltage and magnetic field dependence are investigated. It is found that the supercurrent can be switched on/off by modulating the gate voltage, behaving as a supercurrent field-effect transistor. Under an out-of-plane magnetic field, the SQUID shows an anomalous magnetic field -enhanced superconductivity behavior near the Dirac point. An in-plane magnetic field experiment shows a typical π periodicity of a critical current with the rotation angle. Our work realizes the implementation and characterization of nanowire SQUID structures, which is a significant step toward integrating Dirac semimetal nanowires into scalable superconducting networks for braiding non-Abelian quantum states. |
