Majorana Fermions are theoretical particles that are their own antiparticles, meaning they can annihilate themselves. They were proposed by the Italian physicist Ettore Majorana in 1937. These particles are significant in the field of quantum mechanics and particle physics because they could help explain certain phenomena in the universe. In addition to their theoretical importance, Majorana Fermions have potential applications in quantum computing. They could be used to create more stable qubits, which are the building blocks of quantum computers. This stability could lead to advancements in technology and a better understanding of topological phases in materials.
