Majorana fermions are particles that are their own antiparticles. In the context of topological superconductors, they emerge at zero energy at the material's edges or vortices. These particles are of immense interest because they can be used to create topological qubits, which are more stable and less prone to decoherence compared to conventional qubits. This stability arises from their non-abelian statistics, making them highly suitable for quantum error correction.
