Coherential Interference Core (CIC) — Consolidated Technical Note v2.2: Scientific-Computational Validation Results

This technical note consolidates the scientific-computational validation of the Coherential Interference Core (CIC) V2 as a candidate photonic pre-filter for vector similarity search in semantic embedding spaces. Across validation campaigns v2.1 and v2.2, the operator preserves neighborhood geometry with 97.7–99.9% Spearman fidelity over 384, 768, and 1024 dimensions, using multiple embedding models, external queries, dimensional stress tests, shuffle controls, and phase-noise robustness checks.

A first-order energy and latency estimate indicates a plausible order-of-magnitude advantage window at large scale (approximately 20× lower energy and 18× lower latency versus GPU H100), subject to verifiable photonic hardware conditions including insertion loss, optical parallelism, and ADC/DAC overhead.

This document summarizes the abstract CIC operator and its scientific-computational validation. The methodological clarification of the D=32 benchmark and the photonic surrogate is presented separately in a dedicated April 2026 addendum.
