They compared it to graphene which has been a revolutionizing substance in the semiconductor industry.  Apparently the performance is magnitudes faster than other substance and transistor combinations.  Yet they think this new state could be even faster:

Quantum spin liquids are mysterious states of matter which are thought to be hiding in certain magnetic materials, but had not been conclusively sighted in nature.

The observation of one of their most intriguing properties—electron splitting, or fractionalisation—in real materials is a breakthrough.

That is mind boggling.  What types of applications do you think this would be used in besides potentially new microprocessors?
