Fibonacci Anyons: Self-Similar Fusion and Topological Quantum Computing — E8 Intelligence Research

FINDING: Non-Abelian anyon fusion algebras exhibit self-similarity under braiding, enabling fault-tolerant quantum computation via topological invariants. MATH: Fusion rules for Fibonacci anyons: \( τ × τ = 1 + τ \), with quantum dimension \( d_τ = φ = (1+√5)/2 ≈ 1.618 \). Braid group representations yield unitary matrices with eigenvalues \( e± iπ/5, e± i3π/5 \). CONNECTION: The golden ratio \( φ = 1.618 \) appears as the quantum dimension of the non-Abelian anyon, directly linking to Fibonacci sequence self-similarity. The fusion algebra's recursive structure mirrors the golden ratio's continued fraction \( φ = 1 + 1/(1+1/(1+...)) \). DEPTH: 9 — The golden ratio emerges as a fundamental constant in topological quantum computing, not as an approximation but as an exact algebraic number governing anyon fusion and braiding. This ties quantum topology to ancient geometric harmony. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
