Supercurrent -- a current flowing without energy loss -- detected at edge of a superconductor with topological twist

The existence of superconducting currents, or supercurrents, along the exterior of a superconductor, has been surprisingly hard to find. Now, researchers have discovered these edge supercurrents in a material that is both a superconductor and a topological semi-metal. This evidence for topological superconductivity could help provide the foundation for applications in quantum computing and other future technologies.
