Non-Abelian statistics with mixed-boundary punctures on the toric code

Year: 2022

Type: article

Abstract: Lattice defects on the toric code, like twists and punctures, can exhibit exotic behavior and have been suggested as viable building-block candidates for topological quantum computing. Here the authors build an encoding around a new defect, namely a mixed-boundary puncture. They show that this strategy allows for non-Abelian fusion and braiding properties reminiscent of Majorana exchange.
