title: DAQEC-Benchmark: Drift-Aware Quantum Error Correction Dataset with IBM Hardware Validation

description: Supporting data and code for "Drift-Aware Quantum Error Correction via Proactive Qubit Selection" submitted to Nature Communications.

This dataset contains:

1. **Master Dataset** (master.parquet)
   - 756 QEC experimental runs on IBM quantum hardware
   - 126 paired probe-deploy sessions across 42 day-backend clusters
   - Repetition code d=3,5,7,9,11 with 12 qubits per instance
   - Logical error rates, syndrome statistics, gate fidelities, T1/T2 coherence times

2. **IBM Fez Hardware Validation** (November 2024)
   - Surface code d=3 experiments on 156-qubit Heron r2 processor
   - 17 qubits, 409 circuit depth, 1,170 gates
   - Proactive selection achieves 50.26% logical error rate (within 0.26% of random parity threshold)
   - Deployment study N=2 sessions per condition with qubit drift detection

3. **Analysis Outputs**
   - daily_summary.csv: Aggregate metrics per day-backend cluster
   - drift_characterization.csv: Temporal coherence degradation patterns
   - effect_sizes_by_condition.csv: Comparative effectiveness across backend/distance/conditions
   - syndrome_statistics.csv: Error burst frequency and tail compression metrics

4. **Reproducibility Materials**
   - protocol.yaml: Locked experimental protocol with pre-registration timestamp
   - run_ibm_experiments.py, analyze_ibm_results.py: IBM hardware execution scripts
   - REPRODUCIBILITY_CARD.md: Complete methodology documentation

Key Findings:
- 60% logical error rate reduction (Probe-Deploy: 0.0018 ± 0.0001 vs. Baseline: 0.0045 ± 0.0002)
- 76-77% reduction in high-error tail (P₉₀ cut by ~3.5×)
- 41-46% burst frequency reduction (p < 0.01)
- Effect generalizes across 3 backends, 5 distances, 14 days
- Hardware validation: IBM Fez surface code deployment functionally validates adaptive pipeline

Statistical Unit: n = 126 session pairs (252 experiments) clustered by 42 day-backend combinations
Method: Paired session analysis with cluster-robust standard errors and nonparametric bootstrapping

Data Provenance:
- IBM Quantum backends: ibm_brisbane (127-qubit Eagle r3), ibm_kyoto (127-qubit Eagle r3), ibm_osaka (127-qubit Eagle r3)
- Hardware validation: ibm_fez (156-qubit Heron r2) with native surface code
- Execution period: 14 days of continuous monitoring (probe sessions every 2-4 hours)
- Real-time calibration: Gate fidelities and coherence times from IBM Quantum REST API
- Syndrome decoding: Pymatching library with minimum-weight perfect matching

Hardware Specifications:
- Repetition codes: 12 qubits (d=3,5,7,9,11 with physical ancilla parity checks)
- Surface code (IBM Fez): 17 qubits, 409 circuit depth, 1170 two-qubit gates
