Structural Differentiation Quantum Theory (SDQ) v1.2: Structural Origin of Correlation and Emergent Time

We propose a minimal and falsifiable structural reformulation of quantum theory. In SDQ, correlation is not fundamental but emerges from accumulated structural connectivity. We introduce a structural correlation function S(Ls) and demonstrate that its decay is governed by structural connectivity distance and temporal evolution. This leads to a unified interpretation of correlation, information, and time as manifestations of structural differentiation. Unlike standard quantum mechanics, SDQ predicts measurable deviations in correlation under varying structural connectivity. This work provides a direct experimental pathway to distinguish structural quantum theory from standard quantum mechanics.This framework introduces a structural reinterpretation without modifying the mathematical formalism of quantum mechanics.
