Protected Majorana states for quantum information

Quantum technology has the potential to revolutionize computation, cryptography, and simulation of quantum systems. However, quantum physics places a new demand on information processing hardware: quantum states are fragile, and so must be controlled without being measured. Researchers at the Niels Bohr Institute have now demonstrated a key property of Majorana zero modes that protects them from decoherence. The result lends positive support to the existence of Majorana modes, and goes further b...
