Cluster state as a noninvertible symmetry-protected topological phase

S Seifnashri, SH Shao - Physical Review Letters, 2024 - APS
We show that the standard 1+ 1 DZ 2× Z 2 cluster model has a noninvertible global
symmetry, described by the fusion category Rep (D 8). Therefore, the cluster state is not only …
