Phase 3 Entanglement/Tomography Analysis Manifest

Date: 2026-05-20

Inputs

  • Counts artefact: data/phase3_entanglement_tomography/entanglement_tomography_live_ibm_marrakesh_2026-05-20T004334Z.json
  • Reference CSV: data/phase3_entanglement_tomography/entanglement_observable_rows_2026-05-07.csv
  • Backend: ibm_marrakesh
  • Job IDs: d86g7h1789is738vkreg, d86ggpis46sc73f6v170

Outputs

  • JSON summary: data/phase3_entanglement_tomography/entanglement_tomography_summary_2026-05-20.json
  • Observable rows: data/phase3_entanglement_tomography/entanglement_tomography_rows_2026-05-20.csv
  • Observable rows SHA256: b280db120f9f13dfb8dd6b8d4e2e6a86a86feff714e2514be01bd5b3ed95bd83

Result Snapshot

  • Observable rows: 54
  • Mean absolute deviation from exact reference: 0.12989296537986128
  • Maximum absolute deviation from exact reference: 0.5560906424788263
  • Readout-mitigated mean absolute deviation from exact reference: 0.12930386230559288
  • Readout-mitigated maximum absolute deviation from exact reference: 0.5648340543137427

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
