Every 2D translation-invariant topological CSS code is local-unitarily equivalent, at the maximal anyon-preserving translation symmetry, to stacks of toric codes and product states, with an explicit polynomial-time construction.
This proves the diagonal form in Eq

Decoupling 2D translation-invariant topological CSS codes
Every 2D translation-invariant topological CSS code is local-unitarily equivalent, at the maximal anyon-preserving translation symmetry, to stacks of toric codes and product states, with an explicit polynomial-time construction.
