Majorana fermions and their use for quantum computation
I will explain how to use a superconductor to decompose a single electron into two Majorana fermions. These are special particles that are identical to their own antiparticles. The original electron stays hidden from measurement and thus protected from decoherence as long as the two Majorana fermions do not interact. I will show how to use this protection together with interchanging of the Majorana fermions to implement a quantum computation scheme protected by parity conservation. I will also describe how to implement this scheme by combining existing superconducting qubits with Majorana fermions.
