Emergent Reality in Quantum from Classical Transition

Quantum Darwinism is a leading framework for explaining how classical reality emerges from a quantum universe—the environment redundantly encodes the pointer state information of quantum systems, enabling multiple independent observers to reach consensus about reality. However, a fundamental question has remained unanswered: Why does the environment possess this capacity for redundant recording? This paper proposes, within the information-potential conversion framework, that the redundant recording mechanism of quantum Darwinism is the physical realization of the information-potential conversion consensus protocol—the environment, acting as the physical medium for information-potential conversion, redundantly encodes system information, providing consistent conversion records for independent information processing units, from which classical reality emerges. Based on this interpretation, three testable quantitative predictions are proposed: (1) In superconducting quantum circuits, when system complexity exceeds a critical threshold, the efficiency of redundant recording should exhibit an abrupt transition—a signal of the information-potential conversion phase transition of the consensus protocol from “quantum critical” to “classically locked”; (2) There should exist a precise linear relationship between functional information and information-potential conversion energy consumption: each additional bit of functional information doubles the minimum heat dissipation required for record stabilization; (3) Consensus strength—the stability of classical reality—should be positively correlated with the number of information processing units participating in the consensus protocol, and a critical number exists at which the consensus phase transition occurs. quantum Darwinism, information-potential conversion, consensus protocol, classical emergence, redundant recording, functional information

This work aims to address unresolved questions in physics through a coherent framework built upon a unified understanding of the interdependence of gravity, quantum physics, and classical mechanics, ultimately leading to the emergence of physical reality. The approach builds upon Madelung’s quantum hydrodynamic representation, extending it by incorporating stochastic perturbations from gravitational background noise (GBN). The consequent stochastic quantum hydrodynamics model (SQHM) bridges the quantum and classical domains, unveiling a natural quantum-to-classical coexistence. For the first time, the model provides a theoretical foundation for the Lindemann constant and can be experimentally tested via a photon entanglement experiment. It also accurately reproduces the experimental data for the fluid–superfluid transition in helium. The framework resolves long-standing theoretical conflicts between quantum mechanics and classical mechanics, addresses the EPR paradox, and provides novel insights into the emergence of flowing time in 4-D spacetime and the evolution of the universe, potentially accommodating free will. The proposed framework highlights the inadequacy of both deterministic laws and a purely measure-dependent conception of reality governed by unpredictable probabilistic evolution.

We propose an effective framework to account for the emergence of time, history, and classical reality from quantum dynamics. The approach distinguishes between processes that occur dynamically and those that consolidate as physical past through the formation of stable, redundant, and irreversible records. We introduce the principle of self-reinforced stability of histories, according to which only certain evolutions can persist as effective physical history under semiclassical dynamics. Within this framework, the quantum–classical transition is described as a continuous and dynamically accelerated crossover, rather than a collapse or a sharp threshold. Classical time emerges locally together with history as an effective ordering associated with irreversibility, and the uniqueness of the past arises as a dynamical consequence rather than a postulate. The framework is compatible with standard quantum mechanics and general relativity within their domains of validity, introduces no inflated ontology, and is falsifiable through the structural exclusion of entire classes of non-observable phenomena.
