Translationally-invariant prime-qudit (\(q=p\)) stabilizer codes with \(m\) qudits per unit cell have been classified in dimensions \(D\in\{1,2\}\) in the thermodynamic limit, up to equivalence under local constant-depth Clifford circuits.
Any 1D (2D) code can be converted to several copies of the 1D repetition code (prime-qudit 2D surface code) along with some trivial codes \cite{arXiv:1607.01387} (\cite{arXiv:1812.11193}).

where \(\mathsf{Z}\) denotes taking the center of a group.
Code switching may not preserve the logical information and instead implement logical measurements; conditions on \(\mathsf{S}\) and \(\mathsf{F}\) such that qubit stabilizer code switching preserves logical information are derived in \cite[Prop. II.1]{arxiv:2304.01277}.
Clifford operations and Pauli measurements can be expressed as sequences of code switching \cite{arxiv:2401.12017}.
In the context of Abelian topological stabilizer codes, code switching implements \textit{anyon condensation} of any anyons represented by operators in the group \(\mathsf{F}\).
