A Dynamical Spacetime Mechanism for Quantum Entanglement with a Falsifiable Experimental Signature

Quantum entanglement is a central resource of quantum information science, yet its correlations are ordinarily treated as properties of the quantum state rather than as the outcome of an underlying physical process. Here we explore the hypothesis that these correlations are mediated dynamically by a field propagating locally at finite velocity through an extension of ordinary spacetime. The model embeds physical (3,1)-dimensional spacetime in a warped five-dimensional geometry containing an additional timelike coordinate. Within the adopted geometric ansatz, the form of the extended spacetime metric is determined by the five-dimensional vacuum Einstein equations. A massless bulk field in the resulting geometry admits equal-time statistical correlations across arbitrarily distant brane locations, while its source-driven brane response remains governed by a retarded kernel and therefore preserves operational no-signaling. Coupling this field to a Bohm--Bub-inspired collapse scheme provides a possible dynamical realization of entanglement correlations and, under an explicitly stated equivariance condition for the contextual ensemble, reproduces Born statistics. The framework leads to a concrete experimental test. In the detector/collapse realisation developed here, two nominally independent Bell pairs acquire a weak contextual cross-pair correlation. Within this class of realisations, its leading distance dependence is fixed by the bulk zero mode and scales as (l/d)2, where l and d denote, respectively, the intra-pair and inter-pair separations. This cross-pair correlation is absent in standard quantum mechanics for independently prepared systems. It could therefore be tested by varying the distance between two simultaneous Bell experiments using existing photonic technology. Observation of such a signal would support a dynamical spacetime account of quantum entanglement and could have implications for quantum networks employing multiple independent entangled resources.
