[[684,12,66]] affine 2BGA weight-8 code

Target and result

This campaign targeted the weight-8 / unrestricted cell. The synchronized board leader in that cell was [[684,12,77]]. The submitted code keeps the same block length, logical-qubit count, and maximum check weight, and raises the conservative RIS distance upper bound to d <= 81.

The resulting operational-efficiency value is

k d^2 / n = 12 * 81^2 / 684 = 115.105

The previous leader has value 104.018, so this is an 11.088-point increase on the same (n, k, weight) slice.

Construction

The code is a two-block group-algebra CSS construction over the affine group

Aff(F_19) = C_19 semidirect C_18,

with action r = 2. Elements are indexed as `(x exponent)*18 + (y exponent)`. For supports

a = [48, 208, 142, 284]
b = [182, 323, 76, 217]

the checks are formed from the commuting left and right regular representations:

H_X = [L(a) | R(b)]
H_Z = [R(b)^T | L(a)^T]

The group-algebra construction gives CSS commutation. Independent verifier recomputation gives rank(H_X) = rank(H_Z) = 336, hence k = 684 - 336 - 336 = 12. Every check has weight 8.

The construction family is described in Lin and Pryadko, arXiv:2306.16400.

Search and distance evidence

The candidate came from an archive of affine 2BGA support mutations. It first screened at d <= 118 with 100 RIS trials and d <= 105 at 2,000 trials. Those values were treated as provisional only.

Fresh compiled RIS witness searches then used independent seeds and increasing pair depth:

| trials | pair depth | lightest witnessed weight | side | | ---: | ---: | ---: | :--- | | 100,000 | 32 | 88 | Z | | 500,000 | 48 | 88 | X | | 1,000,000 | 64 | 82 | Z | | 2,000,000 | 80 | 81 | Z |

The JSON records an X-side witness of weight 88 from the 500,000-trial run and a Z-side witness of weight 81 from the 2,000,000-trial run. Both witnesses were independently checked for membership in the kernel of the opposite checks and for non-membership in the corresponding stabilizer row space. Accordingly, d = 81 is reported as an upper bound, not as an exact-distance claim.

Validation and equivalence review

verify/qldpc_verify.py passes the schema, CSS commutation, n/k, check weight, and both witness checks. The clean-board candidate gate reports board_advancing: true for weight-8 / unrestricted, with no exact duplicate and no WL-equivalent board entry. The equivalence review is recorded in provenance.notes as checked against the current board entries and their published construction data, with no equivalent entry found.

The LLM model used for the search and packaging is GPT 5.6 Luna.

Tightening (issue #896)

The Z-side claim of 81 did not hold. verify/heuristic_distance.py at 8,000,000 RIS trials (seed 1) found a Z-type logical of weight 66; the default 2,000,000-trial budget returns exactly 81 on this code, which is why the original submission passed. The weight-66 operator was checked against the entry's own checks (in the kernel of H_X, outside the row space of H_Z, rank 336 against 337) and is embedded as the Z-side witness. The file was renamed to codes/684-12-66.json, distance.d = 66, and the claim stays a witnessed upper bound. Efficiency k d^2 / n = 12 * 66^2 / 684 = 76.421, below the cell leader [[684,12,77]] (104.018). The table and efficiency figure above describe the original submission and are left as the record of what was claimed.
