Physicists achieve nonabelion-based topological quantum states.
Physicists have created non-Abelian anyons, a type of exotic particle that could help make quantum computers less error-prone. The particles exist only as information inside a quantum computer, but their linking properties could make quantum computers more fault-tolerant. The researchers used a quantum computer to create virtual particles and move them around so that their paths formed a Borromean-ring pattern. The appearance of the pattern was confirmed by measurements of the state of the ions during and after the operation.
