# Experimental data for “Mitigation of Crosstalk Errors in Quantum Measurements” This repository contains the experimental and simulator data used in the finalrevision of *Mitigation of Crosstalk Errors in Quantum Measurements*. It is areviewer-facing subset of the authors' working archive: only records that mapto a table or data-bearing figure in the paper are included. The source manuscript reviewed for this release has SHA-256 digest`411dc4a7b0bd424acc013a86da3a1f13ac24af274c9a629fa65c2157f2389a7d`.The manuscript PDF itself is not redistributed here. ## Paper-to-data map | Paper item | Device/data set | Processed file | Supporting raw data ||---|---|---|---|| Figures 6–7 | `FakeBrisbane` | — | `data/raw/fake_brisbane/` || Table I | `ibm_fez`, q67 | `data/processed/table_I.csv` | `data/raw/ibm_fez_2026-08-31/n1/` || Table II | `ibm_fez`, q66–q67 | `data/processed/table_II.csv` | `data/raw/ibm_fez_2026-08-31/n2/` || Table III | q66–q67 experiments | `data/processed/table_III.csv`, `table_III_state_level.csv` | `data/raw/ibm_aachen_pair_q66_q67_2026-09-07/` || Tables IV–V | `ibm_fez`, 3–4 qubits | `data/processed/table_IV.csv`, `table_V.csv` | `data/raw/ibm_fez_2026-08-31/n3/`, `n4/` || Figure 9 | `ibm_fez`, 1–4 qubits | `data/processed/figure_9_repeat_level.csv`, `figure_9_aggregate.csv` | `data/raw/ibm_fez_2026-08-31/` || Figure 10 | `ibm_aachen`, q65–q67 | `data/processed/figure_10_repeat_level.csv`, `figure_10_aggregate.csv` | `data/raw/ibm_aachen_q65_q67_2026-09-14/` || Table VI | `AerSimulator` using an `ibm_fez` noise model | `data/processed/table_VI.csv` | `data/raw/aer_ibm_fez_4q_2026-09-19/selection/` || Figure 12 | same simulator experiment | `data/processed/figure_12.csv` | `data/raw/aer_ibm_fez_4q_2026-09-19/` | Figures not listed above are conceptual diagrams, device-layout graphics, ortheoretical plots and do not have separate experimental records. ## Directory structure ```textdata/ processed/ Flat CSV files matching the paper's tables and plotted series raw/ Counts, reconstructed POVMs, protocol arrays, and validation datascripts/ verify_release.py Check checksums, structure, and expected row counts assemble_from_workspace.py Maintainer-only release assembly/provenance scriptMANIFEST.sha256 SHA-256 digest for every released file``` NumPy archives use `.npz`; count streams use compressed JSON Lines; theFakeBrisbane records use MATLAB `.mat`. JSON files describe optimizers,reconstruction diagnostics, state preparations, and aggregate metrics. ## Verification Only Python 3's standard library is needed for the integrity check: ```bashpython3 scripts/verify_release.py``` MATLAB is required only to rerun the legacy FakeBrisbane analysis scripts.The processed CSV files can be inspected without MATLAB or Qiskit. ## Selection and exclusions - Hardware QDT shot counts, reconstructed POVMs, protocol parameters, and validation outcomes supporting the reported results are included.- The simulator release includes reconstructed strategy POVMs, factorization products, validation counts/probabilities, exact references, selections, and summaries. Per-setting simulator QDT count archives (over 280MB) are omitted because they are deterministically reproducible and are not needed to check Table VI or Figure 12.- API credentials, account/service identifiers, cloud job identifiers, calibration snapshots, quota/usage records, transpiled circuit binaries, and machine-local paths are excluded. ## Terms No license is granted by this repository.
