Jones Polynomial from Quantum R-Matrices: Unifying Knot Theory and Topological Quantum Computation — E8 Intelligence Research

FINDING: The Jones polynomial is a knot invariant constructible from quantum R-matrices (braid group representations), and its evaluation at roots of unity yields the computational resource for topological quantum computation — the same algebraic structure underlies both knot theory and TQFT. | MATH: Jones polynomial V_K(t) ∈ ℤ[t^{±1/2}]; skein relation: t⁻¹V(L₊) − tV(L₋) = (t^{1/2} − t^{−1/2})V(L₀). Braid group representation: ρ: B_n → GL(V^⊗n) via R-matrix satisfying Yang-Baxter equation (R⊗I)(I⊗R)(R⊗I) = (I⊗R)(R⊗I)(I⊗R). At t = e^{2πi/k}, the representation factors through Temperley-Lieb algebra TL_n(q) with q + q⁻¹ = −(t^{1/2} + t^{−1/2}). Quantum dimension d = −(q + q⁻¹) = [2]_q. Modular tensor category (MTC) data: fusion rules N_{ij}^k, S-matrix, T-matrix (topological spin), satisfying (ST)³ = e^{2πic/8}·S² (modularity). | CONNECTION: Root-of-unity evaluation t = e^{2πi/k} connects to: (1) quantum group U_q(sl₂) at q = e^{iπ/k} — deformation parameter is a root of unity, truncati Author: Andrew Stewart Caldin, Independent Researcher, UK.
