Description
CSS code constructed from linear binary codes whose parity-check or generator matrices are incidence matrices of points, hyperplanes, or other structures in finite geometries. These codes can be interpreted as quantum versions of FG-LDPC codes, but some of them [2,3] are not strictly QLDPC.

- \([[7,1,3]]\) Steane code — The Steane code is the \(m=1\) member of the \([[2^{2m}+2^{m}+1,1,>2^{m}]]\) PG-QLDPC code family that is constructed from codes corresponding to lines and affine charts in \(PG(2,2^m)\) via the CSS construction [3; Def. 4.9].
Cousins
- Finite-geometry LDPC (FG-LDPC) code — Quantum versions of PG-LDPC and EG-LDPC codes can be constructed via the CSS construction [1–3].
- Projective geometry code — PG-QLDPC codes are constructed from linear binary codes whose parity-check or generator matrices are incidence matrices of structures in finite geometries.
- Generalized homological-product qubit CSS code — Iterative tensor products of PG-QLDPC codes yield codes whose stabilizer-generator weights scale almost logarithmically with \(n\) [3].
