They would form Majorana Fermions that would change their physical properties if the time direction was reversed, and so would be enormously useful in Quantum Computers because they would be much less susceptible to environmental noise and thus could remain quantum entangled far longer than everyday particles that are not Majoranas can. The only trouble is that Majorana Fermions exist in theory but nobody knows if they exist in reality.
