Experiments to find Majorana signals are performed by loading a nanowire into a dilution refrigerator capable of cooling it down to close to absolute zero. Credit: HGA Architects and EngineersA shadow has fallen over the race to detect a new type of quantum particle, the Majorana fermion, that could power quantum computers. As someone who works in this area, I’ve become concerned that, after a series of false starts, a significant fraction of the Majorana field is fooling itse...
