It From Qubit: Spacetime Emergence from Quantum Entanglement

The reconciliation of quantum mechanics and general relativity remains one of the most profound challenges in modern physics. This paper introduces and rigorously investigates a novel framework proposing that spacetime emerges from quantum entanglement in a lower-dimensional quantum system. We develop a precise mathematical mapping between entanglement structures and geometric properties of emergent spacetime, demonstrating how Einstein's field equations can be derived from fundamental quantum entanglement dynamics. Our approach provides a unified perspective on quantum mechanics and general relativity, offering potential resolutions to long-standing problems, including the black hole information paradox. We extend this framework to cosmological scenarios and discuss experimental predictions, representing a significant step towards a complete theory of quantum gravity. This work not only advances our understanding of the nature of space, time, and gravity as emergent phenomena but also suggests new avenues for empirical investigation of quantum gravitational effects.
