• 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.

  Gravity is derived from an entropic action coupling matter fields with geometry. The proposed entropic action is the quantum relative entropy between the metric of spacetime and the metric induced by the matter fields. A canonical quantization of this field theory could bring new insights into quantum gravity.

  We consider a non-relativistic quantum system interacting with gravitational waves. We employ the consistent histories approach to quantum mechanics to define a fluctuation relation for this system. As a result, thermodynamic entropy must be produced in the system due to its unavoidable interaction with the quantum fluctuations of spacetime.

  We generalize the Hamiltonian picture of General Relativity coupled to classical matter, known as geometrodynamics, to the case where gravity is described by a Quantum Field Theory in Curved Spacetime. In our approach there is no non-dynamic background structure, apart from the manifold of events, and the gravitational and quantum degrees of freedom have their dynamics inextricably coupled. An important feature of this work is the use of Gaussian measures over the space of matter fields and of Hida distributions to define a common superspace to all possible Hilbert spaces with different measures, to properly characterize the Schrodinger wave functional picture of QFT in
