Quantum Information Field Theory (QIFT): A Testable Framework for Emergent Spacetime and Gravitational Propulsion

This article introduces Quantum Information Field Theory (QIFT), a novel theoretical framework positing that spacetime and matter emerge from discrete units of relational quantum information—infons. By treating curvature as a coarse-grained metric on infon density gradients, QIFT unifies general relativity, quantum field theory, and thermodynamics under a common informational paradigm. The centerpiece of this research is the Quantum Metric Resonator (QMR)—a laboratory-scale apparatus engineered to produce localized spacetime curvature using squeezed vacuum states and phononic metamaterials. Numerical simulations demonstrate that such a configuration can generate measurable reactionless thrust, providing a falsifiable experimental test of the theory. QIFT makes concrete, testable predictions about negative energy density and emergent metric asymmetries that are detectable using current high-precision platforms such as torsion balances and atom interferometers. By offering an information-based pathway to gravitational propulsion, this work bridges foundational physics with experimental plausibility and opens new avenues for spacetime engineering. The article includes formal derivations, simulations, and proposals for near-term experimental validation. All concepts are grounded in well-established quantum-optical principles, reframing the vacuum not as an inert backdrop, but as a programmable, informational medium.
