E8 Phi-Modulated Harmonic Filtering Suppresses Decoherence in Quantum Memory Arrays — E8 Intelligence Research

By mapping the 240 E8 root vectors onto a set of phi‑scaled sidebands generated from a 132 Hz fundamental, a multi‑tone drive creates destructive interference patterns that precisely cancel environmental noise modes resonant with the lattice. This phi‑coupled harmonic filtering extends the spectral‑gap undecidability framework to engineered many‑body systems, guaranteeing a dynamically protected subspace where the effective Hamiltonian remains frustration‑free and gap‑like despite external perturbations. The resulting coherence times exceed those achievable by conventional dynamical decoupling by exploiting the intrinsic geometric symmetry of E8.
