Quantum Measurement Resolved: Entropy-Weighted Causal Collapse in the Quantum Causal Entropy (QCE) Framework

The quantum measurement problem arises from the coexistence of continuousunitary evolution governed by the Schrödinger equation and the apparentnon-unitary collapse of the wavefunction during measurement. Althoughdecoherence theory explains the suppression of interference throughenvironmental interactions, it does not by itself provide a physicalselection mechanism determining the realized outcome. In this work wepresent a dynamical resolution of the measurement problem within theQuantum Causal Entropy (QCE) framework, in which quantum evolution isgoverned by entropy-weighted causal transitions. Measurement interactionsintroduce path-dependent entropy injection that exponentially suppresseshigher-entropy causal branches, producing a continuous entropy-drivenselection of a dominant outcome without invoking an external projectionpostulate. The framework reproduces the Born-rule probabilities in thelow-entropy limit and predicts experimentally testable deviations inregimes involving large-scale entangled states and entropy-controlledmeasurement environments. These results provide a causal-thermodynamicfoundation for quantum measurement dynamics and suggest new experimentalprobes of entropy-driven quantum state selection.
