Resonant Emergence Theory (RET): A TM–BM Information-Theoretic Framework for Quantum State Collapse and the Measurement Problem

The quantum measurement problem — why and how a wavefunction in superposition collapses to a definite state upon observation — remains unresolved after a century of quantum mechanics. Existing interpretations (Copenhagen, Many-Worlds, Bohmian mechanics, Decoherence, Relational QM) each address the problem partially, yet none provides a unified physical mechanism grounded in established information-theoretic quantities. This paper introduces Resonant Emergence Theory (RET), a new interpretive framework that identifies wavefunction collapse as a Resonance Event — the moment at which the quantum state of a system achieves sufficient information-theoretic overlap with the Bold Memory (BM) structure of its environment.RET operationalises Bold Memory as the von Neumann entropy S(ρ_env) of an environmental system, Temporary Memory (TM) as the incoming quantum state (density matrix) of the system under observation, and Resonance as quantum fidelity F(ρ_TM, ρ_env). The collapse condition is formally expressed as R(TM, BM_env) × S(ρ_env) ≥ θ_c, where θ_c is a critical information-density threshold. This formulation is shown to be consistent with, and an extension of, the Lindblad master equation and standard decoherence theory, while providing a physical interpretation of why the environment causes wavefunction collapse.Five postulates are presented: superposition as unresolved continuity, measurement as a resonance event (requiring no conscious observer), wave-particle duality as pre- and post-resonance phases, entanglement as shared BM structure (no FTL communication), and quantum coherence as the cost of continuity. Three falsifiable experimental predictions are proposed, including a BM-threshold experiment feasible with current cavity QED technology.
