Majorana 1: Topological Qubits Claimed, But Braiding and Error Thresholds Undisclosed — E8 Intelligence Research

FINDING: Microsoft's Majorana 1 chip claims topological qubit hardware using Majorana zero modes, but the public evidence (videos, arXiv abstract) does not yet disclose the specific braiding statistics or error-correction thresholds; the mathematical core remains the non-Abelian anyon model. | MATH: The relevant framework is the Ising anyon model (SU(2)₂ Chern-Simons theory). Key constants: quantum dimension d = √2 for Majorana modes; braid matrices generate the Clifford group (not universal without π/8 phase gate); fusion rules: σ × σ = 1 + ψ (where 1 is vacuum, ψ is fermion). Topological protection requires gap Δ >> k_B T; error rate suppressed as exp(-L/ξ) where L is wire length, ξ is coherence length. No new constants or ratios appear in the public data. | CONNECTION: The Ising anyon model's quantum dimension d = √2 relates to the golden ratio via the Fibonacci anyon model (d = φ = 1.618), but Majorana-based systems are *not* Fibonacci — they are simpler.
