   The above condition guarantees that the \(X\)-stabilizer generators, defined in the symplectic representation as rows of \(H_X\), commute with the \(Z\)-stabilizer generators associated with \(H_Z\).

   Encoding is based on two related \hyperref[code:binary_linear]{binary linear codes}, an \([n,k_X,d^\prime_X]\) code \(C_X\) and \([n,k_Z,d^\prime_Z]\) code \(C_Z\), satisfying \(C_X^\perp \subseteq C_Z\). The resulting CSS code has \(k=k_X+k_Z-n\) logical qubits and distance \(d\geq\min\{d^\prime_X,d^\prime_Z\}\). The \(H_X\) (\(H_Z\)) block of \(H\) \eqref{eq:parity} is the parity-check matrix of the code \(C_X\) (\(C_Z\)). The requirement \(C_X^\perp \subseteq C_Z\) guarantees \eqref{eq:comm}.
