Non-Abelian quantum Hall states and anyon braiding
In some quantum Hall states, quasiparticles called non-Abelian anyons store information in how they are wound around each other, so that swapping them performs an operation that depends on the order of swaps. The $5/2$ state in gallium arsenide and half-integer states in bilayer graphene are the main candidates, but their identity and braiding are still being established.
Why it matters
Proving non-Abelian statistics would establish a new kind of quantum particle and the physical basis of topological quantum computing.
