Structural Coherence, Entanglement, and Bell-Test Analysis

This work develops a structural interpretation of quantum entanglement and teleportation that avoids common misconceptions about transmission, transport, or nonlocal influence. Entanglement is treated not as a physical channel but as a shared global quantum state whose correlations cannot be reduced to local descriptions. Using the standard LOCC formulation of teleportation as a completely positive trace‑preserving map, we show that teleportation reconstructs reduced quantum states while necessarily discarding global correlations with the environment. This structural asymmetry excludes any interpretation in terms of physical transport or disappearance, and clarifies why teleportation preserves information without relocating physical systems. We introduce an operational criterion based on environmental reconfiguration: any genuine physical transport must induce detectable changes in the local environment. The absence of such reconfiguration in teleportation parallels the modern understanding of the double‑slit experiment, where loss of coherence arises from environmental coupling rather than observer‑dependent effects. Finally, we illustrate these distinctions through a minimal decoherence model and through analysis of loophole‑free Bell‑test data, where nonlinear correlations persist even when standard entanglement witnesses vanish. Together, these results provide a coherent physical interpretation of entanglement and teleportation without modifying the standard quantum formalism.
