Phase 3 Entanglement/Tomography Analysis Manifest

Date: 2026-05-20

Inputs

  • Counts artefact: data/phase3_entanglement_tomography/entanglement_tomography_live_ibm_fez_2026-05-20T014536Z.json
  • Reference CSV: data/phase3_entanglement_tomography/entanglement_observable_rows_2026-05-07.csv
  • Backend: ibm_fez
  • Job IDs: d86h4jlg7okc73el3ra0, d86h5d9789is738vlt7g

Outputs

  • JSON summary: data/phase3_entanglement_tomography/entanglement_tomography_summary_2026-05-20_ibm_fez.json
  • Observable rows: data/phase3_entanglement_tomography/entanglement_tomography_rows_2026-05-20_ibm_fez.csv
  • Observable rows SHA256: 40801f8ce562e462c3b051b6cd4026b48480fb76770c7f164251c5de550efca1

Result Snapshot

  • Observable rows: 54
  • Mean absolute deviation from exact reference: 0.15282093077862535
  • Maximum absolute deviation from exact reference: 0.47901490766488014
  • Readout-mitigated mean absolute deviation from exact reference: 0.1513169450615788
  • Readout-mitigated maximum absolute deviation from exact reference: 0.4868750566558935

Readout Mitigation

  • Method: tensor_product_single_qubit_inverse
  • Calibration circuits: 4
  • Boundary: independent single-qubit readout inversion only; not a full 16-state correlated readout calibration and not a ZNE/PEC result

Boundary

reduced-Pauli observable analysis only; no scalable tomography, quantum advantage, or backend-general claim
