Version 7 – May 2026 (Current Version) This version contains minor refinements and clarifications to the theoretical framework and experimental predictions. The core claims and structure remain consistent with Version 6. Abstract We present a phenomenological framework in which spacetime curvature can, in principle, be engineered through controlled modulation of quantum entanglement. The model is built on three experimentally supported pillars: (1) gravitationally induced entanglement (GIE), recently demonstrated in tabletop experiments; (2) mature technology for creating and controlling entanglement in Rydberg atom arrays; and (3) recent theoretical results showing that warp metrics are possible with positive energy densities only. We adopt a minimal assumption: that nature entangles essentially all relevant degrees of freedom in ordinary matter. From this we recover Newtonian gravity and derive a relation between local entanglement modulation and spacetime curvature. We propose the Quantum Entanglement Geometry Engine (QEGE) as a controllable experimental platform to test whether macroscopic curvature effects can be produced and measured using current quantum technology. The framework makes concrete, falsifiable predictions for near-term experiments and remains consistent with General Relativity in the classical limit.
