How this certificate was produced
  • This job used the certified ZCC-v0.1 path. The simulator was run with state renormalization disabled, so the final state's norm deficit equals the exact weight discarded by every truncation performed during simulation — call this quantity eps.
  • By the Eckart-Young theorem, eps is an exact accounting of discarded information, not an estimate. The reported error bound is the square root of twice eps, a mathematically rigorous ceiling on the error of any single outcome probability, established in this one run rather than inferred by comparing separate runs.
