Quantum information theory has the potential to revolutionize computation, cryptography, and simulation of quantum systems. However, quantum states are fragile, and unwanted interactions with the environment destroy the information before it can be manipulated successfully. Now, a breakthrough experiment by researchers affiliated with Station Q Copenhagen has 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 by showing that the information contained in these modes is exponentially protected, as predicted theoretically. The results have been published in Nature.
