Eight T states per round from the fewest noisy inputs

Magic-state factories take a large share of the cost of a fault-tolerant quantum computer. A protocol that yields eight good T states per round from fewer noisy inputs, at a fixed output error, makes a factory level smaller.

Instance files

Each JSON file defines one instance of this problem. Instances differ by number of outputs, input error rate and output error ceiling. The verifier reads the same files, and the verifier bundle contains all of them together with an accepted example.
