Abstract: FINDING: Anyons are 2D quasiparticles whose worldlines form braids in (2+1)D spacetime; quantum gates are implemented by topological braiding, making qubits fault-tolerant by construction. | MATH: 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 σ_j = σ_j σ_i for |i−j|≥2. Fibonacci anyons: fusion rule τ⊗τ = 1 ⊕ τ, quantum dimension d_τ = φ = (1+√5)/2 ≈ 1.618. Ising anyons: d_σ = √2, non-universal (Clifford only). | CONNECTION: The Fibonacci anyon quantum dimension is exactly the golden ratio φ = 1.618; its inverse 1/φ = φ−1 = 0.618. Braiding matrices for Fibonacci anyons are built from φ and √φ, embedding the golden ratio directly into the gate set. The Yang–Baxter equation is the algebraic form of the third Reidemeister move — a crystallographic-style symmetry relation on the braid group. | DEPTH: 8 FINDING: Topological quantum computation encodes logical qubits in the degenerate ground-state manifold of a 2D system; information is st Author: Andrew Stewart Caldin, Independent Researcher, UK.
