Fibonacci Anyons and the Golden Ratio in Topological Quantum Computation — E8 Intelligence Research

Published Jul 25, 2026• 0 citations

Abstract

FINDING: Fibonacci anyons realize non-Abelian statistics with fusion rules governed by the golden ratio, enabling topological quantum computation. MATH: Fusion rules: τ × τ = 1 + τ, where τ is the Fibonacci anyon. Quantum dimension d_τ = φ = (1+√5)/2 ≈ 1.618. The number of fusion channels for n anyons grows as F_{n+1} (Fibonacci numbers). Braiding matrices yield non-Abelian representations of the braid group B_n. CONNECTION: The golden ratio φ appears directly as the quantum dimension, linking topological phases to the same ratio found in Penrose tilings, quasicrystals, and 5-fold crystallographic symmetry. The Fibonacci sequence governs fusion state counting, echoing growth patterns in nature and base-60 harmonic ratios (φ ≈ 1.618, 1/φ ≈ 0.618). DEPTH: 9 — Direct embedding of φ into fundamental quantum statistics; bridges topology, number theory, and condensed matter physics; provides a concrete path to fault-tolerant quantum computing via non-Abelian anyons.
