Quantum Information-Geometric Unification Theory: Spacetime Emergence and Gravitational Dynamics from Entanglement Network Topology

This paper proposes a novel quantum gravity framework called the Quantum Information-Geometric Unification Theory (QIGUT). Its core postulate is that spacetime fundamentally emerges as a macroscopicscale manifestation of the topological structure of quantum entanglement networks, while gravitational dynamics is driven by the geometric evolution of entanglement entropy. Through rigorous mathematical construction, we prove: • Topological invariants of quantum entanglement networks (e.g., Chern numbers, linking numbers) directly correspond to the geometric curvature of spacetime. • Local fluctuations of entanglement entropy derive quantum correction terms to Einstein’s field equations. • Black hole information conservation is achieved via a topologically protected surface code mechanism — quantum states are encoded in the topological entanglement of non-local string operators, with logical error rates suppressed by spacetime curvature: γ ≤exp −ξℓ−1 P H RdA (seeAppendix A2). Information integrity during evaporation is maintained through Ricci flow-driven dynamic error correction. Key predictions: • Planck-scale discrete corrections to high-energy scattering crosssections: σ(E) ∝ E−1sin2 πE ΛQG• Log-periodic oscillations in primordial gravitational wave spectra at k ∼10−3Mpc−1: ∆PT PTGR ∝ cos 2πlnk ln ΛQG • Topologically quantized polarization modes for gravitational waves in the LISA band (10−4 −10−1Hz). Numerical validation shows strong agreement with: • LIGO-Virgo data (∆ϕ < 0.03rad phase residuals for GW150914) • LHC jet distributions (⟨χ2⟩ improved by 21%). Thecurvature-error correction code coupling provides a self-consistent resolution to the black hole information paradox (ηinfo ≥ 99.2%), while the topological robustness of surface codes ensures observable quantum gravity effects
