How this certificate was produced
  • This certificate reports ZHF-v0.1, the hardware fidelity protocol: how closely a real quantum processor's measured output matches the ideal distribution for the same circuit, as opposed to the accuracy of a classical approximation.
  • Verification mode is direct: the same circuit was additionally simulated exactly on a classical computer (feasible here because it uses at most 24 qubits). The reported Hellinger fidelity is the statistical overlap between the hardware's measured counts and that exact ideal distribution, on a scale from 0 (no overlap) to 1 (identical).
  • Counts are raw hardware output: no error mitigation, post-selection, or readout correction has been applied. Any deviation from the ideal distribution reflects the physical noise of the device.
