This paper introduces a novel framework for wave function collapse driven by an entropy threshold S_{\text{crit}} . The proposed model uses a Lindblad-type master equation to describe collapse dynamics triggered when the environment’s entropy exceeds a critical value. By quantifying the transition from quantum superposition to classical outcomes, this theory addresses long-standing challenges in the measurement problem. Key contributions include: 1. A mathematical framework connecting environmental entropy with wave function collapse. 2. Experimental proposals involving superconducting qubits and optical interferometry. 3. Comparisons with existing theories, such as GRW and decoherence models. Potential applications range from enhancing quantum error correction to explaining the emergence of classical structures during cosmic inflation. This work bridges quantum mechanics and thermodynamics, offering a testable hypothesis for the quantum-to-classical transition.
