Most efficient weight-6 qLDPC codes with exact distance
A quantum memory needs many logical qubits, each protected by a high distance, from as few physical qubits as possible. The efficiency k·d²/n measures that trade-off for codes whose checks hardware can measure with short circuits.
Instance files
Each JSON file defines one instance of this problem. Instances differ by physical qubit limit. The verifier reads the same files, and the verifier bundle contains all of them together with an accepted example.
