Universal topological phase of 2D stabilizer codes

arXiv:1103.4606 · doi:10.1088/1367-2630/14/7/073048

Abstract

Two topological phases are equivalent if they are connected by a local unitary transformation. In this sense, classifying topological phases amounts to classifying long-range entanglement patterns. We show that all 2D topological stabilizer codes are equivalent to several copies of one universal phase: Kitaev's topological code. Error correction benefits from the corresponding local mappings.
