Topological Superconductors
Topological superconductors are a special class of materials that exhibit unique properties due to their topological order. They combine superconductivity, where materials can conduct electricity without resistance, with topological features that protect certain quantum states from disturbances. This makes them promising for applications in quantum computing.
One of the most exciting aspects of topological superconductors is their potential to host Majorana fermions, which are exotic particles that can exist in these materials. These particles are theorized to be useful for creating robust qubits, the building blocks of quantum computers, due to their non-abelian statistics and resistance to decoherence.
