Quantum multi-dimensional parity-check (QMDPC) code[1]
Description
High-rate low-distance CSS code whose qubits lie on a \(D\)-dimensional rectangle, with \(X\)-type stabilizer generators defined on each \(D-1\)-dimensional rectangle. The \(Z\)-type stabilizer generators are defined via permutations in order to commute with the \(X\)-type generators.
For example, the \(D=2\) square geometry corresponds to a \([[n^2,n^2-4n+2,4]]\) code, with \(X\)-type stabilizer generators defined on rows and columns.
Protection
The general construction for a \(D\)-dimensional rectangle with sides \(n_i\) yields a \([[\prod_{i=1}^{D}n_{i},2\prod_{i=1}^{D}(n_{i}-1)-\prod_{i=1}^{D}n_{i},2^{D}]]\) code family.
