Majorana's wires
Experiments on nanowires have shown evidence of solid-state analogues of the particles predicted by Ettore Majorana more than 70 years ago. Although stronger confirmation is still to come, these first observations have already fuelled expectations of fundamental results and potential applications in quantum information technology.
