Dynamic Harmony Structural Stress-Test Series. This paper evaluates Quantum Darwinism as a proposed mechanism for the emergence of classical structure from quantum systems. The analysis examines whether environment-induced redundancy and decoherence satisfy the structural conditions required for genuine emergence within the Dynamic Harmony framework. Using the Phase Non-Substitutability Test introduced in Paper 0 and the architectural boundary criterion developed in Paper 0B, the paper analyzes whether the proliferation of environmental records constitutes a redefinition of system architecture or remains a configurational rearrangement within the existing quantum state space. The results clarify the relationship between decoherence, environmental encoding, and the structural requirements for Type-2 emergence. This paper forms part of the Dynamic Harmony Structural Stress-Test Series, a research program that evaluates major theories of emergence across physics, biology, and complex systems through adversarial structural analysis.

Dynamic Harmony Structural Stress-Test Series. This paper evaluates the problem of unifying microscopic quantum dynamics with macroscopic classical behavior. The analysis examines whether proposed mechanisms linking these scales satisfy the structural conditions required for genuine emergence within the Dynamic Harmony framework. Using the Phase Non-Substitutability Test introduced in Paper 0 and the architectural boundary criterion developed in Paper 0B, the paper analyzes whether the transition from microscopic quantum dynamics to macroscopic classical systems represents a true architectural redefinition or remains a configurational rearrangement within an existing state space. The analysis clarifies the structural conditions under which unified dynamical descriptions can account for the emergence of stable macroscopic organization.

Dynamic Harmony Structural Stress-Test Series. This paper evaluates the Ghirardi–Rimini–Weber (GRW) objective collapse model as a candidate mechanism for the emergence of classical behavior from quantum systems. The analysis examines whether collapse dynamics satisfy the structural conditions required for genuine emergence within the Dynamic Harmony framework. The paper applies the Phase Non-Substitutability Test introduced in Paper 0 and the architectural boundary criterion developed in Paper 0B to determine whether collapse processes produce a transformation in system architecture or whether they remain configurational rearrangements within an existing quantum state space. The analysis clarifies the relationship between stochastic collapse dynamics and the structural requirements for Type-2 emergence.

Quantum Darwinism extends the traditional formalism of decoherence to explain the emergence of classicality in a quantum universe. A classical description emerges when the environment tends to redundantly acquire information about the pointer states of an open system. In light of recent interest, we apply the theoretical tools of the framework to a qubit coupled with many bosonic subenvironments. We examine the degree to which the same classical information is encoded across collections of (i) complete subenvironments and (ii) residual ``pseudomode'' components of each subenvironment, the conception of which provides a dynamic representation of the reservoir memory. Overall, significant redundancy of information is found as a typical result of the decoherence process. However, by examining its decomposition in terms of classical and quantum correlations, we discover classical information to be nonredundant in both cases i and ii. Moreover, with the full collection of pseudomodes, certain dynamical regimes realize opposite effects, where either the total classical or quantum correlations predominantly decay over time. Finally, when the dynamics are non-Markovian, we find that redundant information is suppressed in line with information backflow to the qubit. By quantifying redundancy, we concretely show it to act as a witness to non-Markovianity in the same way as the trace distance does for nondivisible dynamical maps.
Quantum Darwinism describes how a classical, objective world emerges when a system's information is redundantly copied into its environment. Existing theory is largely static: it asks whether a given state already has this objective structure. This paper develops the complementary dynamical picture — how objectivity emerges and why it is stable. It builds a genuine "renormalization group," a physicist's tool for tracking how a system looks as one zooms out, and applies it to the environmental record. The central finding is that objectivity is a fixed point of this zooming-out flow: an objective state stays objective at every scale, and — strikingly — the requirement of scale-invariance forces the records to be genuinely classical. The flow has two stable end-states, an "objective" phase and a scrambled "encoded" phase, separated by a sharp transition at a critical broadcast rate. The paper proves that a natural information measure decreases irreversibly along the flow toward objectivity, giving the emergence of classicality a definite arrow, analogous to celebrated "c-theorems" in the physics of critical phenomena. A known model of the objectivity–scrambling transition is recovered as a special limit. Every quantitative claim is reproduced by self-testing code, and the core theorems are additionally verified by proof-checking software. In short: classicality has a direction. Like heat flowing one way, the world coarse-grains toward objectivity and never back — a c-theorem for the quantum-to-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
Does objective reality create survivors, or do survivors create objective reality? This paper presents experimental evidence that Quantum Darwinism—the emergence of objective reality through environmental redundancy—is not a generative mechanism of the universe, but a structural artifact of viability. Using a quantum collision model simulation integrated with Breathing Boundary Learning (BBL), we investigate the relationship between system survival (coherence) and information propagation (redundancy). Key Findings: Viability Controls Information Flow: The magnitude of total information shared with the environment (ISE) is strictly regulated by the system's "viability slack" (rest fraction). Unregulated interaction (no_gate) leads to maximal information leakage but immediate system collapse (decoherence). Structural Invariance of Redundancy: Surprisingly, the structure of Darwinian redundancy (Rδ) remains invariant across different gating protocols. This suggests that objectivity is a fundamental form of information that persists whenever a system manages to survive. The Role of BBL: The BBL protocol does not "create" objectivity; it acts as a viability filter that locates the optimal "breathing rhythm" where both system survival and objective reality can coexist. Implications: This work provides the physical foundation for the "Ethics as Viability" framework proposed in the Resonant Fractal Cosmology (RFC) series. It demonstrates that the ethical imperative to "pause and question" (RFC-166, RFC-170) is not merely a philosophical stance but a physical requirement for the persistence of reality itself. Methodology: Sequential collision model with N=8 environmental qubits. Comparative analysis of no_gate, random_rest, and bbl_gate protocols. Evaluation metrics: Mutual Information Profile, Redundancy (Rδ), and System Coherence.
