Non-Abelian Anyon Braiding for Topological Qubits via Braid Group Representations — E8 Intelligence Research

FINDING: Anyon braiding for topological qubits relies on non-Abelian statistics in 2D systems, with braid group representations encoding quantum information. MATH: Braid group \( B_n \) generators \( σ_i \) satisfy \( σ_i σᵢ₊₁ σ_i = σᵢ₊₁ σ_i σᵢ₊₁ \) and \( σ_i σ_j = σ_j σ_i \) for \( |i-j|>1 \). Anyon fusion rules: \( a × b = ∑_c Nab^c c \). Quantum dimension \( d_a \) satisfies \( d_a d_b = ∑_c Nab^c d_c \). Fibonacci anyons: \( τ × τ = 1 + τ \), with \( d_τ = φ = (1+√5)/2 ≈ 1.618 \). Braiding matrices are unitary representations of \( B_n \). CONNECTION: Fibonacci anyon quantum dimension \( d_τ = φ = 1.618 \) — the golden ratio. This is a direct geometric harmony constant. The braid group is related to the mapping class group of punctured surfaces, linking to modular tensor categories and the Jones polynomial (knot invariants).
