Experimental Validation of Quantum Entanglement on IBM's 156-Qubit Heron Processor: A PBR-Inspired Test of Wave Function Realism

This dataset contains the complete experimental results, analysis code, and manuscript for a test of wave function ontology based on the Pusey-Barrett-Rudolph (PBR) theorem, executed on IBM's 156-qubit Heron r2 quantum processor (ibm_fez) on December 9, 2025. KEY ACHIEVEMENT:We achieved a quantum correlation of ⟨Z₀Z₁⟩ = 0.930 ± 0.010 and concurrence of 0.931 ± 0.010 on real NISQ hardware, demonstrating 96.1% fidelity compared to ideal simulator predictions. KEY RESULTS:- Correlation: 0.9302 (93% quantum correlation on hardware)- Concurrence: 0.9310 (strong entanglement preserved)- Fidelity: 96.1% (exceptional for NISQ devices)- Circuit depth: 4 logical gates, 8-9 transpiled- Hardware: IBM Quantum Heron r2 (156 qubits)- Execution date: December 9, 2025 CONTENTS:- Full manuscript (34-page PDF)- Raw experimental data (JSON, CSV)- Complete analysis code (Python/Qiskit)- Visualizations (4 publication-quality figures)- IBM Quantum job IDs for verification- Citation file and documentation SIGNIFICANCE:This experiment validates that current NISQ hardware can maintain sufficient quantum coherence for applications requiring genuine entanglement. The 93% correlation value exceeds thresholds required to rule out simple hidden variable models, supporting wave function realism while acknowledging nuanced philosophical implications (Hossenfelder, 2024). REPRODUCIBILITY:All data, code, and methods are openly available. IBM Quantum job IDs provided for independent verification.
