A Majorana fermion is a type of particle that is its own antiparticle, meaning it can annihilate itself. Named after the Italian physicist Ettore Majorana, these particles are predicted to exist in certain conditions, such as in superconductors or topological materials. Their unique properties make them of great interest in the field of quantum computing. The study of Majorana fermions is significant because they could lead to advancements in quantum information technology. They are theorized to be stable and less susceptible to errors, which is crucial for building reliable quantum computers. Researchers are actively searching for experimental evidence of these elusive particles.
