Majorana fermions are particles that are their own antiparticles. In condensed matter physics, zero-energy Majorana fermions obey non-abelian statistics, and can be used in fault-tolerant topological quantum computation. They are thus the subject of extensive studies. However, as Majorana fermions carry no electric charge, detecting them experimentally is still a challenge. A current noise study now provides a direct method for the detection of these novel particles.
