Majorana Braiding as Non‑Abelian Anyon Exchange in Topological Quantum Computing — E8 Intelligence Research

**FINDING:** Microsoft's "Topological Quantum Computer Explained" – Majorana zero‑mode braiding as non‑Abelian anyon exchange. | **MATH:** Braiding operators \(Bᵢⱼ\) satisfy the braid group relations \(B_i Bᵢ₊₁ B_i = Bᵢ₊₁ B_i Bᵢ₊₁\); unitary representation \(B_i = exp\!(π/4γ_iγᵢ₊₁)\) with Majorana operators \(γ_i\) (\(γ_i^2=1,\{γ_i,γ_j\}=2δᵢⱼ\)). Logical qubit encoded in fermion parity \(iγ_1γ_2 = ±1\). | **CONNECTION:** The braid group is the Artin group of type \(Aₙ₋₁\), whose Coxeter diagram maps to the \(E_8\) root lattice (crystallographic symmetry). The phase \(π/4\) is a 8‑fold rotational symmetry (angle \(45^∘\)), linking to the golden ratio via \(cos 45^∘ = √2/2\) and the 0.618/1.618 ratio in the eigenvalue spectrum of the Kitaev chain. | **DEPTH:** 8 --- **FINDING:** "Microsoft kündigt den weltweit ersten topologischen Quantenchip an – Majorana 1 erklärt" – Experime Author: Andrew Stewart Caldin, Independent Researcher, UK.
