A general stabilizer code has one binary symplectic check matrix S = (A | B): generator i acts as X on Ai and Z on Bi, Y where both. A CSS code is the special case where every row is pure X or pure Z; here every code has at least one mixed generator (a code that is CSS up to a Hadamard on some qubits is filed as a duplicate of its CSS image, not listed twice). These codes are ranked on their own board because the quantities the CSS board reads per side have no side here:
| CSS board | this board | |
|---|---|---|
| checks | H_X, H_Z | S = (A | B), isotropic: A Bᵀ + B Aᵀ = 0 |
| k | n − rank H_X − rank H_Z | n − rank S |
| distance | d = min(d_X, d_Z), one witness per side | one d: the minimum Pauli weight of a nontrivial logical operator (Y counts once); one Pauli-operator witness |
| check weight w | row weight | |Ai ∪ Bi| |
| kd²/n, g, tracks | unchanged; the primary-track cells are computed the same way, but carry the code type, so a record here is never a record there | |
| certificate | MILP per side | not built yet: every entry stands as d ≤ |
| circuit tier | memory circuits per basis | not accepted yet: syndrome extraction needs a general stabilizer-measurement schedule |
Symplectic doubling maps any [[n, k, d]] stabilizer code to a CSS code [[2n, 2k, d′]] with d ≤ d′ ≤ 2d, so the two boards are linked; halving that map is how the highest-rate entries here were built. See the schema, tracks, and how to submit a stabilizer code (bring S, or A and B, as an .npz).

Primary tracks
Computed grid of locality × check weight, derived from H and the layout, not self-declared. Each cell lists its Pareto frontier, ranked by the selected score (kd²/n, or geometric efficiency g for codes with a verified layout); codes tied on the score rank by the lowest (n, k) pair. The code count filters the table below to that cell. Membership nests: a tighter cell’s codes also compete in the looser ones. In the g view, the seeded surface/toric tilings are not raced; they set the ceiling g is normalized to (surface code = 1) and appear dimmed below the ranking.
