Majorana fermions are theoretical particles that are their own antiparticles, meaning they can annihilate themselves. 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. Researchers believe that Majorana fermions could be used to create more stable qubits, which are the building blocks of quantum computers. This stability arises from their non-abelian statistics, allowing for error-resistant quantum information processing. The search for these particles continues to be a significant focus in modern physics.
