Near-optimal high-rate surgery from linear PCPPs
Alexander Cowtan, Benjamin Ide
A central problem for surgery with quantum Low-Density Parity Check (LDPC) codes is the design of auxiliary systems which measure large sets of logical operators in parallel, while…

Algebraic Aspects of Boundaries in the Kitaev Quantum Double Model
Alexander Cowtan, Shahn Majid
We provide a systematic treatment of boundaries based on subgroups with the Kitaev quantum double model in the bulk. The boundary sites are representations of…
