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.
  • 30 exceeds the exact-reference limit of 24 for qasm2 programs; companion-circuit fidelity mode is not yet enabled
  • 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.
