discovered the Majorana fermions

it seems he was right !!!

Particles that correspond to their antiparticles were predicted by Ettore Majorana in 1937. (paper on Nuovo Cimento)
Now, the first observation of that prediction in the field of nanotechnology and superconductivity. (paper on science)

Experiments on double beta decay (DBD) without neutrino emission are in progress since the beginning of 2000 to confirm that these neutrino are Majorana particles. Still waiting for increasing statistics.

An important discovery whose implications could affect the future of quantum computers
