Israeli led researchers at the Weizman Institute of Science have presented evidence for particles capable of storing quantum information — without needing error correction. These particles are termed non-Abelian anyons. Standard particle physics entails only fermions and bosons. However, exceptions do occur, called anyons. Abelian anyons are akin to fermions in behavior. Non-Abelian anyons have ‘odd’ properties useful, it is thought, for topological quantum computing (TQC). TQC does not demand error correction to make the qubits useful. Why no error-correction needed? Locally, perturbations of the anyons may exist but the errors do not map globally where it matters.
