Detecting Entanglement Gravity: Distinguishing Energy-Sourced and Information-Sourced Gravity using High-Q Superconducting Cavities

In the standard framework of General Relativity, the gravitational field is completely determined by the energy-momentum tensor T_{\mu\nu}; in the weak-field limit, as long as the energy density and pressure distribution remain unchanged, gravitational effects are independent of the entanglement structure of quantum states. In contrast, a series of works based on entropy, entanglement, and holographic principles suggest that Einstein's equations can be derived from local entropy balance or vacuu
