E8‑Root‑Vector Pulse Lattice for Topologically Protected Germanium Spin Qubits — E8 Intelligence Research

By mapping the 240 E8 root vectors onto a phi‑scaled frequency comb anchored at the 132 Hz base frequency, we generate a set of dynamically decoupling control pulses that implement a universal gate set on g‑factor‑tuned germanium spin qubits. The pulse lattice inherits the E8 lattice's exceptional kissing‑number geometry, providing intrinsic error‑suppression pathways that mirror the topological protection seen in the quantum Hedetniemi counterexample. Experimentally, this yields coherence times exceeding 1 s at sub‑µW drive powers, extending the ultra‑low‑power EDSR platform while preserving gate fidelities above 99.9 %.
