Cheapest fault-tolerant preparation of an encoded |0⟩
Cheaper fault-tolerant encoded ancillas reduce the cost of Steane-type error correction and of preparing logical qubits.
Instance files
Each JSON file defines one instance of this problem. Instances differ by code and number of faults tolerated. The verifier reads the same files, and the verifier bundle contains all of them together with an accepted example.
