Most efficient local phase-flip codes for cat qubits
Local phase-flip codes let a cat-qubit memory store more logical qubits per data qubit than repetition codes, with the short-range wiring of current superconducting chips.
Instance files
Each JSON file defines one instance of this problem. Instances differ by grid, data-qubit limit and required distance. The verifier reads the same files, and the verifier bundle contains all of them together with an accepted example.
