Quantum Advantage and Anyonic Braiding: Probing Non-Commutative Structures in Hilbert Space — E8 Intelligence Research

FINDING: Tianyan-287 (105-qubit superconducting processor) demonstrates quantum advantage via random circuit sampling, while Quantinuum's H2 realizes non-Abelian braided anyons — both probing non-commutative group structures in Hilbert space. MATH: - Tianyan-287: 105 qubits, Zuchongzhi 3.0-class; fidelity metrics imply effective Hilbert space dimension ~2^105 ≈ 4.06×10^31. Random circuit sampling exploits linear cross-entropy benchmark (XEB) — no closed-form equation given, but advantage rests on statistical distinguishability of ideal vs. noisy output distributions. - Non-Abelian anyons: braid group B_n generators σ_i satisfy σ_i σ_{i+1} σ_i = σ_{i+1} σ_i σ_{i+1} (Yang–Baxter), and σ_i^2 ≠ 1 (unlike permutations). Topological quantum computation encodes logic in fusion spaces of dimension given by Fibonacci anyons: d_φ = φ = (1+√5)/2 = 1.618…, with fusion rule τ×τ = 1 + τ. CONNECTION: - Fibonacci anyon dimension φ = 1.618 — direct geometric harmony constant. Braid matrices f Author: Andrew Stewart Caldin, Independent Researcher, UK.
