Fibonacci Anyons: Universal Quantum Gates via Non-Abelian Braiding — E8 Intelligence Research

FINDING: Topological quantum computation via non-Abelian anyon braiding, specifically Fibonacci anyons, encodes qubits in degenerate state spaces where braid operations generate the Fibonacci fusion rules and yield universal quantum gates. | MATH: Fibonacci anyon fusion rule: τ ⊗ τ = 1 ⊕ τ (golden anyon). Dimension of Hilbert space for n anyons grows as Fibonacci numbers: dim(H_n) = Fₙ₋₁ (with F_0=0, F_1=1). Braid generators σ_i satisfy Yang-Baxter: σ_i σᵢ₊₁ σ_i = σᵢ₊₁ σ_i σᵢ₊₁, and σ_i σ_j = σ_j σ_i for |i-j|≥2. Single-qubit braiding gates compiled via brute-force optimization (arXiv:2008.03542) — the key constant is the golden ratio φ = (1+√5)/2 ≈ 1.618, which appears as the quantum dimension d_τ = φ. | CONNECTION: Direct geometric harmony: Fibonacci anyons have quantum dimension exactly φ = 1.618 (and its inverse 0.618 = 1/φ). The fusion space dimension sequence (1,1,2,3,5,8,...) is the Fibonacci sequence — the same ratio governing pentagonal symmetry (5-fold crystallogr Author: Andrew Stewart Caldin, Independent Researcher, UK.
