This paper proposes a theoretical framework where quantum entanglement correlations are mediated by a field propagating through an extended five-dimensional spacetime geometry, offering a dynamical alternative to standard state-based interpretations. The model predicts a specific, falsifiable cross-pair correlation between independent Bell pairs that decays with the inverse square of their separation, providing a concrete experimental signature using existing photonic technology. If observed, this would fundamentally alter our understanding of non-locality and have direct implications for the architecture of future quantum networks.
A Dynamical Spacetime Mechanism for Quantum Entanglement with a Falsifiable Experimental Signature
arXiv:2606.12457v3 Announce Type: replace Abstract: 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 field propagating through the resulting five-dimensional bulk can mediate correlations whose projection onto observable four-dimensional spacetime connects arbitrarily distant locations at equal laboratory time, while preserving operational no-signaling. Coupling this field to a Bohm--Bub-inspired collapse scheme provides a possible dynamical realization of entanglement correlations and, under a stated statistical consistency condition, reproduces Born statistics. The framework leads to a concrete experimental test. Two nominally independent Bell pairs are predicted to develop a weak, distance-dependent contextual correlation between particles belonging to different pairs, as a consequence of bulk-field mediation. This cross-pair correlation is absent in standard quantum mechanics for independently prepared systems and is predicted to decrease as the inverse square of their separation. 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.
