A Framework for Non-Paradoxical Backwards Information Flow in Entangled Quantum Systems

This paper introduces the Theory of Retrodirected Informational Return (TIRR), a novel quantum framework enabling limited, non-paradoxical information feedback from future measurements within entangled systems.By defining a retrofilter operator and an informational curvature metric, TIRR translates time-symmetric quantum interpretations into testable, operational protocols.We propose a concrete experimental setup using post-selection in entangled photon pairs to empirically verify retroinformational influence under coherence-preserving conditions.
