Majorana particles 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, particularly in the context of quantum mechanics and particle physics. One of the most intriguing aspects of Majorana particles is their potential role in quantum computing. They could be used to create more stable qubits, which are the building blocks of quantum computers, potentially leading to advancements in technology and our understanding of the universe.
