Superconductivity on the Edge (IMAGE) Princeton University Caption Researchers at Princeton have discovered superconducting currents traveling along the outer edges of a superconductor with topological properties, suggesting a route to topological superconductivity that could be useful in future quantum computers. The superconductivity is represented by the black center of the diagram indicating no resistance to the current flow. The jagged pattern indicates the oscillation of the superconductivity which varies with the strength of an applied magnetic field.
