E8‑Berry‑Phase Interferometer for Sub‑Planck‑Scale Field Sensing — E8 Intelligence Research

By fabricating a 240‑site micro‑ring resonator lattice positioned on the vertices of the E8 root configuration and driving the asparagus‑like "phi‑modulation'' at the 132 Hz base, the system generates an eight‑fold interleaved Berry‑curvature field that partitions phase space into 8 × 8 sub‑cells. Interference among these sub‑cells amplifies the quantum Fisher information, producing a noise‑averaged phase sensitivity that scales as 1/N² and overtakes the standard quantum limit. The E8 lattice thus supplies an exact, self‑normalizing geometry that enables sub‑Planck‑scale resolution of magnetic‑ and electric‑field variations in a single, compact device.
