Abstract

We propose a fundamental duality between the geometric properties of spacetime and the informational content of quantum fields. Specifically, we establish that the curvature of spacetime is directly related to the entanglement entropy of quantum states, with geometric invariants mapping to informational measures. This framework modifies Einstein's field equations by introducing an informational stress-energy tensor derived from quantum entanglement entropy. Our findings have implications for black hole thermodynamics, cosmology, and quantum gravity, suggesting that quantum information fundamentally shapes the structure of spacetime. We incorporate this informational stress-energy tensor into Einstein's field equations, leading to modified spacetime geometry, particularly in regimes of strong gravitational fields, such as near black holes. We compute corrections to Newton's constant (G) due to entanglement entropy contributions from various quantum fields and explore the consequences for black hole thermodynamics and cosmology. These corrections include explicit dependence on fundamental constants (h-bar, c, and k_B), ensuring dimensional consistency in our calculations. Our results indicate that quantum information plays a crucial role in gravitational dynamics, providing new insights into the nature of spacetime and potential solutions to long-standing challenges in quantum gravity.
