Abstract
## Binary Failure → Geometry Solution
**Analysis of Findings:**
The search results reveal a critical tension: quantum machine learning (QML) researchers are using neural networks to *predict* entanglement patterns, yet the underlying structure of entanglement is fundamentally geometric (e.g., monogamy of entanglement, tensor network geometries). The "exponential separation" result (Zhenhuan Liu, QIP 2025) shows that quantum learning with vs. without purification diverges exponentially — a binary classifier cannot bridge this gap because it lacks a metric for *state purity* that respects the curved manifold of density matrices.
**Where binary/statistical approaches FAIL:**
1. **Entanglement classification** — Neural nets trained on entanglement measures (concurrence, negativity) fail to generalize across qubit counts because these measures are not invariant under local unitary transformations. A binary classifier sees a 3-qubit GHZ state and a W state as "both entangled" but cannot
