Even-Odd Vacuum Structure in N-Qubit GHZ Structural Coherence: Complete Dataset and Analysis

This dataset accompanies the research paper "Even-Odd Vacuum Structure in N-Qubit GHZ Structural Coherence: Corrected N-Scan with Qiskit Validation" and provides complete experimental data, analysis code, and publication-quality figures for the systematic study of structural coherence in N-qubit GHZ states (N=2-9). Key Findings: Even N systems: Universal symmetric vacuum at λ* = 0.5 Odd N systems: Broken-symmetry vacua at λ* = (2±√2)/4 ≈ {0.146, 0.854} Geometric Structure: √2-based (NOT golden ratio φ) Statistical Significance: 20,000 shots per point, 201 parameter points Scientific Impact: This work provides the quantum geometric foundation for Structure-Residual Cosmology (SRC) theory and establishes a novel classification of multipartite entanglement through even-odd vacuum structure. Contents: Complete manuscript (PDF, 14 pages), LaTeX source code, publication-quality figures (300 DPI), experimental validation report, and comprehensive documentation.
