Topological superconductor

A topological superconductor is a special state of matter that combines properties of superconductors—materials that can conduct electricity without resistance—with unique surface states protected by the material's underlying topology. These surface states host exotic particles called Majorana fermions, which are their own antiparticles, making them promising for robust quantum computing. Unlike conventional superconductors, topological ones have a stable electronic structure linked to their geometry, leading to potential applications in fault-tolerant quantum information processing. In essence, they represent a cutting-edge intersection of physics, topology, and superconductivity with promising technological implications.
