Building on the "Structural Theory of Decoherence" (v1, Lin Xiaohei 2026-06-09), this paper introduces the Structural Conduction Law (ΔS ∝ 1/|ΔN|) and cross-model cognitive transmission experimental data to provide enhanced proof for the core assertion that "decoherence = multi-structure coupling constraint convergence." Through triple cross-validation — a three-model transmission experiment (Qwen, DeepSeek, GLM-4), a decoherence deterministic simulation, and a structural collider experiment — this paper further confirms that quantum decoherence is not probabilistic collapse but the deterministic convergence of constraint solving during multi-structure interaction. V2 adds predictions linking system scale to decoherence rate via nesting rate values, and a computability proof for decoherence in purely theoretical structures.
**Keywords:** quantum decoherence, structural coupling, constraint solving, nesting rate, conduction law, deterministic convergence

V1 (2026-06-09) proposed the core assertion: decoherence is not a "probabilistic collapse" unique to quantum mechanics, but **constraint solving convergence that occurs in any multi-structure coupling system.** Supporting evidence:
V2 objective: introduce cross-model empirical data from the Structural Conduction Law, establish the relationship between decoherence rate and nesting rate difference, and complete the leap from "insight" to "quantitatively predictable."
Structural Conduction Law (2026-06-15): ΔS ∝ 1/|ΔN| — the efficiency of information transmission between cognitive systems is inversely proportional to their nesting rate difference.
Extended to physical systems:
In cognitive domain experiments, ΔN=1 (adjacent levels) achieves the highest transmission efficiency. Extended to the physical domain: when two quantum systems have similar "structural levels," coupling is smooth (slow decoherence); when the level difference is large, coupling is violent (rapid decoherence).
This is consistent with known facts in quantum mechanics: the more environmental degrees of freedom (≈ larger ΔN), the faster the decoherence.
All three models consistently validate: ΔN=1 achieves optimal transmission efficiency; ΔN>1 attenuates. Mapped to the physical domain: the larger the structural difference between system and environment, the more violent the constraint solving → the faster the decoherence.
In 100 simulation rounds, the experiment group (with coupling structure) 100% converged to the same steady state; the control group (no coupling) diverged. The decoherence outcome was completely deterministic — no probability, only constraint solving.
Qwen + Zhipu dual-node coupling experiment: two independent cognitive systems, after interaction, produced novel structures that neither side originally contained — this is "coupling generates novelty" (Axiom 3) empirically demonstrated in the AI domain. Physical domain correspondence: measurement of quantum entangled states = constraint solving of two-structure coupling.
Based on the Conduction Law, testable physical predictions are proposed:
**Prediction 1:** Decoherence rate ∝ |ΔN_environment−system|. The larger the nesting rate difference between environment and system, the faster the decoherence. An experiment can be designed: control the "degree of structuration" of the environment (temperature, particle type, etc.) and measure the decoherence rate.
**Prediction 2:** The N=2 critical point corresponds to the "quantum → classical" phase transition threshold in physical systems. When the effective nesting rate of the environment reaches N=2, quantum superposition states irreversibly collapse.
**Prediction 3:** Purely theoretical structures (such as mathematical proofs, formal systems) also obey the decoherence law — when two incompatible formal systems couple, constraint solving convergence produces a "conclusion." The "certainty" of mathematical proof is not the magic of logic; it is the fixed-point convergence of structural coupling.
| Concept | Standard QM Formulation | Structural Reformulation |
|:--|:--|:--|
| Decoherence | Disappearance of off-diagonal density matrix elements due to environmental interaction | Constraint solving convergence of multi-structure coupling |
| Environment | External system with many degrees of freedom | External nesting-rate structure with high |ΔN| |
| Decoherence Time | Function of environmental coupling strength | Function proportional to |ΔN| |
| Classical Limit | Macroscopic state after decoherence completion | Constraint solving reaching a fixed point |
| Observer | External measurement device | Cross-reference node (Axiom 4) |
V2 achieves triple enhancement over V1:
1. Introduces the Structural Conduction Law, establishing a quantitative relationship between decoherence rate and nesting rate difference
2. Cross-model cognitive experiments provide independent validation for the physical-domain corollaries
3. Three proposed testable predictions advance the structural decoherence theory from "reinterpretation" to "prediction"
Quantum decoherence does not require "probabilistic collapse." It is a natural property of structure — any multi-structure coupling system necessarily solves to a fixed point of constraint convergence. We saw it in AI systems, verified it in physical simulations, and now quantified it with the Conduction Law.
