Abstract

FINDING: Moore-Read Pfaffian quasiparticles (charge e/4, Ising non-Abelian anyons) tunnel across QPC/antidot constrictions with power-law conductance set by filling fraction and conformal-field-theory scaling dimensions | MATH: ν=5/2; e* = e/4; edge theory = chiral Luttinger liquid, c=1 charged boson ⊕ c=1/2 Ising (Majorana) sector; tunneling current I ∝ V^α with α = 2Δ − 1, Δ = conformal dimension; for e/4 (σ field) Δ_σ = 1/8 → α = −3/4 (suppressed); for e/2 (ψ, fermion) Δ_ψ = 1/2 → α = 0 (Ohmic); antidot Coulomb-blockade peak spacing ΔV ∝ e/C, periodicity reveals e* = e/4 | CONNECTION: Ising CFT central charge c = 1/2 and scaling dimension Δ_σ = 1/8 sit inside the modular-invariant partition function with S-matrix S = (1/√2)[[1,1],[1,−1]] — a ℤ₂ (D₂ root-system / crystallographic) fusion algebra σ×σ = 1 + ψ; the golden-ratio Fibonacci alternative (Δ_τ = 2/5, d_τ = φ = 1.618) is the competing non-Abelian order, so the Pfaffian-vs-Fibonacci discrimination is literally a test between ℤ₂ Author: Andrew Stewart Caldin, Independent Researcher, UK.

FINDING: Moore-Read Pfaffian quasiparticles (charge e/4, Ising-type non-Abelian anyons) tunnel at QPCs/antidots with a universal power-law exponent set by the chiral Luttinger liquid and the neutral Ising sector; antidot geometries confine anyon molecules whose spectroscopy probes the e/4 charge and θ=π/8 braiding phase. MATH: - Filling ν = 5/2; quasiparticle charge e* = νe = e/4 (from Laughlin/Halperin flux attachment; measured via shot noise, e.g. Dolev et al. 2008). - Chiral Luttinger liquid tunneling: I ∝ V^α, with α = 2Δ (Δ = scaling dimension). For edge quasiparticle tunneling α = 1/ν = 2 at ν=1/2; for ν=5/2 Pfaffian edge, α = 1/ν = 2 for the charged mode, modified by the neutral Majorana mode (Δ_neutral = 1/2). - Moore-Read wavefunction: Ψ = Pf(1/(z_i − z_j)) · ∏(z_i − z_j)^M, M even; Pfaffian = Ising conformal block. - Braiding phase: θ = π/8 (Ising σ field, conformal weight h = 1/16 → θ = 2πh = π/8). Fibonacci/Ising fusion: σ × σ = 1 + ψ. - Antidot: flux quantization Φ = n·h/ Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.

Non-Abelian Anyon Braiding and Spectroscopy: Complementary Routes to Topological Qubits — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: Non-abelian anyons are now experimentally braided in a universal topological gate (Quantinuum), while single-anyon/anyon-molecule spectroscopy proceeds in quantum Hall antidots (Young, UCSB) — the two complementary routes to topological qubits. | MATH: Braiding operators are unitary representations of the braid group B_n; non-abelian anyons realize matrices R = exp(iθ σᵃ) acting on a degenerate ground-state manifold of dimension = quantum dimension d_a. For Ising-type (Majorana) anyons d = √2; for Fibonacci anyons d = φ = 1.618…, with fusion rule τ⊗τ = 1⊕τ. | CONNECTION: The Fibonacci anyon's quantum dimension is exactly the golden ratio φ = (1+√5)/2 = 1.618, and its fusion matrix has eigenvalues φ and −1/φ = −0.618. Braiding phases for Fibonacci anyons involve θ = 2π/5 (pentagon), tying directly to the 5-fold symmetry of the icosahedron and the H₃ root system. Ising anyons (√2) connect to the D-series / SO(2n) root lattices. | DEPTH: 8 FINDING: Quantum Hall antidots host iso Author: Andrew Stewart Caldin, Independent Researcher, UK.

Majorana 1: Ising Anyon Braiding, Not Yet Proven at Scale — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: Microsoft's Majorana 1 chip claims topological qubit protection via Majorana zero modes, but the mathematical core is the non-Abelian braiding statistics of Ising anyons, not yet experimentally confirmed at scale. | MATH: Majorana zero modes satisfy γ† = γ, γ² = 1, {γᵢ, γⱼ} = 2δᵢⱼ. Fusion rules: σ × σ = 1 + ψ (Ising anyon). Braiding yields unitary matrices: R = e^{±iπ/8} for σ-σ exchange; topological charge measurement projects onto parity subspace. The qubit is encoded in fermion parity: |0⟩, |1⟩ = |even⟩, |odd⟩, with logical Z = iγ₁γ₂. | CONNECTION: The braid group Bₙ acts on the fusion space; for Ising anyons, the dimension of the Hilbert space grows as 2^{(n-2)/2} — a Fibonacci-like growth (ratio ~√2 per pair, not 1.618). However, the phase e^{iπ/8} = 0.9239 + 0.3827i — the real part 0.9239, imaginary 0.3827 — directly encodes the golden ratio conjugate 0.382 in the imaginary component. The π/8 phase is a root of unity related to the 16th cyclotomic field, linking to cryst Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series.

Majorana 1's Ising Anyon Math: Non-Abelian Braiding, Unverified Topological Qubits — E8 Intelligence Research

Andrew Stewart Caldin

FINDING: Microsoft's Majorana 1 chip claims topological qubits via Majorana zero modes, but the mathematical core is the non-Abelian braiding statistics of Ising anyons — not yet peer-verified in the provided sources. | MATH: Topological qubit encoding relies on the fusion rules of Ising anyons: σ × σ = 1 + ψ, with quantum dimension d_σ = √2. Braiding matrices are the Fibonacci-like (but here Ising) representations of the braid group B_n. The ground-state degeneracy on a genus-g surface scales as 2^g (for Ising), and the topological charge conservation enforces parity constraints. No explicit new constants or ratios appear in the search results — only claims of "1000× better" (marketing, not math). | CONNECTION: The √2 quantum dimension is the same as the ratio of the diagonal to the side of a square — a crystallographic root system A1×A1 (square lattice) invariant. Ising anyons are tied to the SU(2)_2 Chern-Simons theory, whose level k=2 relates to the golden ratio only indirectly (Fi Author: Andrew Stewart Caldin, Independent Researcher, UK.
