Most logical qubits with check weight at most 6
Store more logical qubits within the same physical qubit limit and distance requirement.
Instance: Size limit and required distance
Record 12 logical qubits by qarena-baseline · QArena baseline 12 · Reference 12 (Published construction) · What these mean
n ≤ 288, d ≥ 18 (). More logical qubits rank first. Ties are ranked by fewer physical qubits, then lower maximum qubit degree, then submission number (lower first). Each participant appears once, with their best accepted submission. Scores are public; a participant can keep the file itself private.
