Probing the Deep Structure of Quantum Entanglement: A Superluminal Communication Experiment Based on 10-km Ion-Ion Entanglement

The nonlocal correlations of quantum entanglement have been unequivocally confirmed by experiments, yet standard quantum mechanics regards them as a fundamental, irreducible phenomenon. This paper asks: is there a deeper physical structure underlying entanglement? We propose the Instantaneous Teleportation Cosmos (ITC) framework as a theoretical model for such a deep structure, interpreting entangled particles as dual manifestations of the same basal storage unit. This basal structure possesses four core properties: Storage Perfection (P1), Instantaneous Connectivity (P2), Mapping Determinacy (P3), and Manifestation Finiteness (P4). The main obstacle to superluminal communication lies in P4: the randomness of single-shot measurements prevents direct information extraction. However, P4 does not forbid changes in statistical distributions–local modulation at the sender modifies the boundary conditions of the basal storage unit; through P2, this instantly affects the receiver’s basal state; and according to P3, such a change in the basal state necessarily alters the probability distribution at the receiver’s manifestation layer, manifesting as a tiny shift ΔP in the single-party probability. Based on the breakthrough 10‑km ion‑ion entanglement platform, we propose an immediately realizable experimental scheme: using a 7σ confidence standard, we will detect the significance of ΔP via a two‑sample z‑test, and directly measure the response delay with high‑precision timestamps. If ΔP is significantly non‑zero and the delay is much smaller than the light‑travel time, it would provide the first experimental evidence for the deep structure of entanglement; if no signal is observed, we will place stringent upper bounds on ΔP, thereby imposing the strictest test of the no-signaling theorem to date and severely restricting the possible space for a deep structure. The scheme employs the White Rabbit protocol for sub‑nanosecond time synchronization and includes false‑positive elimination measures such as zero‑entanglement control and fiber‑length variation. All necessary techniques are now mature, allowing the experiment to be performed immediately. This experiment constitutes a decisive test for the deep structure of quantum entanglement; regardless of the outcome, it will deepen our understanding of quantum nonlocality and causality.
