`We demonstrate our proposal with a 70-qubit, depth-70 Clifford circuit doped with 468 T gates. We use a total of 97 physical qubits to encode this computation in spacetime codes, effectively suppressing gate error rates by 10× after syndrome post-selection, and yielding a state with a fidelity lower bound of 0.284 with 95% confidence.`
