Entropy-Induced Collapse (EIC) is a theoretical framework that approaches the quantum measurement problem from an information-theoretic perspective. In standard quantum mechanics, the Schrödinger equation describes deterministic unitary evolution of quantum states. However, measurements appear to produce definite classical outcomes. The physical mechanism underlying the transition from coherent quantum superpositions to classical definiteness remains one of the central unresolved issues in the foundations of quantum theory. The Entropy-Induced Collapse framework proposes that collapse-like behavior can be understood as a structural transition in information recoverability rather than as a fundamental stochastic process or a modification of quantum dynamics. In this framework, the global system–environment state evolves unitarily according to the Schrödinger equation. Interactions with the environment progressively distribute phase information across a growing number of environmental degrees of freedom. As long as this information remains recoverable in principle, quantum coherence can be reconstructed. However, once environmental entropy exceeds a critical structural threshold, the information required to reconstruct the coherent state becomes effectively inaccessible. From this perspective, the apparent collapse of the wavefunction corresponds to a transition from recoverable to irrecoverable information rather than to a fundamental dynamical discontinuity. The EIC framework therefore preserves the standard dynamical laws of quantum mechanics while providing a structural explanation for the emergence of classical measurement outcomes. This paper presents the conceptual and structural foundations of the Entropy-Induced Collapse framework. It is the first paper in a four-part research series that develops the EIC framework from theoretical foundations to experimental and engineering implications. The series is organized as follows: 1. Structural entropy threshold for collapse (this paper) 2. Pre-threshold information recoverability dynamics 3. False-collapse statistics in quantum error-correction regimes 4. Experimental architectures and engineering tests of the EIC framework Together, these papers aim to provide a coherent theoretical structure linking quantum measurement, environmental entropy growth, quantum error correction, and experimentally testable diagnostics of collapse-like phenomena.
