Topological Qubits via Non-Abelian Anyons: Braid Group and Majorana Modes — E8 Intelligence Research

Abstract

FINDING: Topological quantum computing leverages non-Abelian anyons (Majorana zero modes) for fault-tolerant braiding operations, with Microsoft's Majorana 1 chip claiming topological qubit hardware. | MATH: Braid group B_n generators σ_i satisfy σ_i σ_{i+1} σ_i = σ_{i+1} σ_i σ_{i+1} and σ_i σ_j = σ_j σ_i for |i−j|≥2; non-Abelian anyons yield unitary representations U(σ_i) with U(σ_i)U(σ_{i+1})U(σ_i) ≠ U(σ_{i+1})U(σ_i)U(σ_{i+1}); Majorana zero modes obey γ_i† = γ_i, {γ_i, γ_j} = 2δ_ij; topological qubit encoded in parity (−1)^{n} = i^{2n} γ_1 γ_2 … γ_{2n}; Fibonacci anyons have quantum dimension φ = (1+√5)/2 ≈ 1.618, fusion rules τ×τ = 1 + τ. | CONNECTION: Fibonacci anyons directly encode the golden ratio φ in their quantum dimension — braiding statistics are governed by the golden ratio; the braid group B_n is isomorphic to the mapping class group of the punctured disk, whose moduli space relates to the modular group PSL(2,ℤ) (base-60 heritage); Majorana zero modes on a 1D nanowire fo Author: Andrew Stewart Caldin, Independent Researcher, UK.
