A Variant of the Bravyi-Terhal Bound for Arbitrary Boundary Conditions
François Arnault, Philippe Gaborit, Wouter Rozendaal +2
We present a modified version of the Bravyi-Terhal bound that applies to quantum codes defined by local parity-check constraints on a -dimensional lattice quotient. Specifically…
