Causal Foundations for Information Integration: Distinguishing Coordination from Correlation in Quantum Measurement

Abstract

Information integration measures quantify coordination in complex systems, but conflate correlation with causation. High mutual information can arise from genuine causal influence, common inputs, or independent dynamics with shared constraints. We introduce a theoretical framework distinguishing these mechanisms through causal efficiency $\rho = \text{TE}/\text{MI}$, the fraction of correlation reflecting genuine information flow rather than self-prediction. We prove that this framework is mathematically equivalent to standard integration measures under bounded distortion, with distortion constants revealing three distinct regimes: (I) high causality where correlation accurately reflects integration, (II) heterogeneous coupling where structure matters, and (III) low causal efficiency where correlation masquerades as coordination. Applied to quantum measurement, we show that the triadic coordination capacity framework (duration, frequency, agency) provides natural context for detecting regime transitions. The formalism makes testable predictions: coordination events should exhibit $\rho > 0.7$ during genuine integration, while decoherence shows $\rho < 0.3$ despite persistent correlation. This establishes rigorous causal foundations for integration theory and characterizes when correlation-based measures succeed or systematically fail.

Observer as a Physical System: A Causal Integration-based Quantum Measurement Model and Its Crucial Experiment

xinwu chen

Abstract This paper proposes a novel framework that reinterprets the observer in quantum mechanics as a physical system governed by causal integration principles. By modeling the observer as an active participant in the measurement process—rather than a passive external entity—we show that quantum collapse can emerge as a natural consequence of the observer’s internal causal structure and information processing constraints. This framework avoids the ad-hoc postulates of standard quantum theory and provides a consistent, ontologically grounded account of measurement. Crucial experimental tests are proposed to validate the predictions of this model, including modified double-slit experiments and precision measurements of quantum correlations. These experiments aim to distinguish between the predictions of our causal integration model and those of conventional quantum mechanics, thereby opening new avenues for experimental investigation into the foundations of quantum theory.

Information–theoretic implications of quantum causal structures

Rafael Chaves, Christian Majenz, David Gross

It is a relatively new insight of classical statistics that empirical data can contain information about causation rather than mere correlation. First algorithms have been proposed that are capable of testing whether a presumed causal relationship is compatible with an observed distribution. However, no systematic method is known for treating such problems in a way that generalizes to quantum systems. Here, we describe a general algorithm for computing information–theoretic constraints on the correlations that can arise from a given causal structure, where we allow for quantum systems as well as classical random variables. The general technique is applied to two relevant cases: first, we show that the principle of information causality appears naturally in our framework and go on to generalize and strengthen it. Second, we derive bounds on the correlations that can occur in a networked architecture, where a set of few-body quantum systems is distributed among some parties. Empirical data can contain information about causation rather than mere correlation. Here Chaves et al. present an algorithm for computing constraints on the correlations arising from a given quantum causal structure, and apply this framework to the information causality principle and networked architectures.

Quantum correlations and causal structures

Issam Ibnouhsein

Recent works in foundations of quantum (field) theory and relativistic quantum information try to better grasp the interplay between the structure of quantum correlations and the constraints imposed by causality on physical operations. Chapter 1 is dedicated to the study of the conceptual implications of quantum nonlocality, a concept that subsumes that of entanglement in a certain way. We detail the recent information-theoretic approaches to understanding the structure of nonlocal correlations, and the issues the latter raise concerning the ability of local observers to isolate a system from its environment. Chapter 2 reviews in what sense imposing Poincare invariance affects entanglement detection and quantification procedures. This invariance ultimately forces a description of all quantum systems within the framework of quantum field theory, which leads to the impossibility of localized finite-energy states and to the divergence of all entanglement measures for local observers. We provide a solution to these two problems by showing that there exists a generic equivalence between a finite spatial resolution of the measurement apparatus and the exclusion of high-energy degrees of freedom from the definition of the observed system. This equivalence allows for an epistemic interpretation of the standard quantum formalism describing nonrelativistic localized systems and their correlations, hence a clarification of the origin of the finite measures of entanglement between such systems. Chapter 3 presents a recent theoretical framework that predicts the existence of correlations with indefinite causal order. In analogy to the information-theoretic approaches to nonlocal correlations, we introduce some principles that constrain the structure of such correlations, which is a first step toward a clear understanding of their physical origin.

Observer as a Physical System: A Causal Integration-Based Quantitative Model

xinwu chen

Abstract The quantum measurement problem remains a foundational challenge due to the lack of an operable physical definition of the "observer." This paper addresses this gap by modeling the observer as a discrete dynamical system with a quantifiable causal structure, characterized by three hierarchical dimensions: Differentiation Degree, Interaction Degree, and Global Integration Degree. From these, we define the Effective Integrated Information Degree (Φ) as a single metric for the system’s information-processing capability. Based on the unitary evolution of quantum mechanics, we derive a testable core relationship: the uncertainty probability P of a measurement outcome decays exponentially with \Phi , i.e., P \propto e^{-\alpha \Phi} . This provides a mechanistic explanation for wave function collapse rooted in the internal dynamics of the observer system. We further establish a universal Mass-Energy-Information Equivalence framework by integrating Einstein’s mass-energy equivalence with Landauer’s principle, proving a rigid conversion between \Phi and the equivalent mass of the system. This work represents a paradigm shift: it transforms the "observer" from a philosophical concept into a calculable, verifiable physical system, and opens an empirically tractable path toward unifying quantum mechanics with fundamental physics. Regardless of experimental outcomes, the model provides a rigorous foundation for resolving the quantum measurement problem and advancing our understanding of the universe’s fundamental laws.

Quantum Liang Information Flow Probe of Causality across Critical Points

Roopayan Ghosh, Bin Yi, Sougato Bose

Investigating causation in the quantum domain is crucial. Despite numerous studies of correlations in quantum many-body systems, causation, which is very distinct from correlations, has hardly been studied. We address this by demonstrating the efficacy of the newly established causation measure, quantum Liang information flow, in quantifying causality across phase diagrams of quantum many-body systems. We focus on quantum criticality, which are highly nonclassical points. We extract causation behavior across a spectrum-wide critical point and a ground state second-order phase transition in both integrable and nonintegrable systems. Across criticality, each case exhibits distinct hallmarks, different from correlation measures. We also deduce that quantum causation qualitatively follows the quasiparticle picture of information propagation in integrable systems but exhibits enhanced quantum nonlocality near criticality. At times significantly larger than the spatial separation, it extracts additional features from the equilibrium wave function, leading to a peak just before the critical point for near boundary sites.

The Ontology of Quantum Mechanics: Coherent Free-State Propagation and Constraint Formation

Hongpu Yang

What is quantum mechanics, constitutionally? This document provides the answer within the Energy-Efficiency Theory framework: quantum mechanics is not an independent set of physical laws, nor a "theory of particles," nor a "theory of measurement." Quantum mechanics is the dynamics of non-matter—the coherent propagation of free-state energy (E_f, E_c = 0) along Type II edges of the constraint network at the optimal cooperative capacity point η ≈ 1. Constraint Dynamics (CND v4.0) describes the dynamics of matter (Being, E_c > 0). Measurement is the constitutional interface between them: a Cut → Encapsulate event at the Type I/Type II boundary that terminates non-matter propagation and creates a persistent matter record. The QM ↔ Measurement Constitutional Duality is the constitutional expression of the Non-Matter/Matter distinction in dynamics. Version 3.1 is a comprehensive constitutional upgrade that preserves all v3.0 content while introducing five core refinements. (i) The Matter/Non-Matter constitutional framework (Particle v3.3) is implanted throughout: QM governs non-matter; measurement is the non-matter → matter constitutional transition; the wavefunction ψ = |ψ| e^{iS/A_EET} is the complex amplitude of non-matter propagation—physically real (ontic), not epistemic, not many-worlds. (ii) Barrier Asymmetry is conditionalized: E_b^melt ≫ E_b^form emerges from Γ(η) decay at η ≠ 1; at η = 1, E_b^form = E_b^melt = A_EET · ω (Inertia v3.4, CLOSED). Quantum coherence is protected by the three-engine architecture. (iii) The decoherence rate is corrected from a contradictory single-factor model to a two-channel additive model distinguishing encapsulation-driven decoherence (∝ f_enc(L)) from efficiency-imbalance-driven decoherence (∝ 1−Γ(η)). (iv) The quantum-to-classical transition is refined from a binary "L ≥ 3" threshold to a three-regime crossover governance (L ≤ 2 quantum, L = 3–4 crossover, L ≥ 5 effective classical), with the L_branch concept distinguishing whole-object coherence (excluded) from collective-coordinate coherence (experimentally observed). (v) The Schrödinger's cat paradox receives its constitutional resolution: the radioactive atom is non-matter (transient constraint events); the cat is matter (E ∈ {0,1} binary). The paradox arises from conflating these two constitutional domains. Ten core constitutional deepenings distinguish v3.1 from its predecessor. DEEPENING-1: The wavefunction's ontic status is systematically situated against all six major QM interpretations (Copenhagen, Many-Worlds, de Broglie–Bohm, QBism, GRW, EET), establishing EET's distinct constitutional position. DEEPENING-2: The five-channel complete constraint Second Law (CND v4.0, CLOSED) is integrated into the quantum measurement framework, unifying passive decoherence, environmental decoherence, and measurement-induced decoherence as three variants of meltdown channel activation. DEEPENING-3: The dual-channel decoherence model unifies elastic decoherence (reversible, ∝ 1−Γ(η)) and plastic decoherence (irreversible, ∝ C(t), measurement collapse) within a single constitutional framework, resolving the measurement problem. DEEPENING-4: The non-matter → matter constitutional transition is established as the three-step measurement dynamics (Difference Detection → Template Matching → Persistent Record Formation), constitutionally anchored in the constraint formation competition framework. DEEPENING-5: The line graph duality (Field v3.1 R4, Particle v3.3 Part VI) is registered as the graph-theoretic foundation of wave-particle duality—not a quantum mystery, but a universal graph-theoretic theorem. DEEPENING-6: QM and GR co-originate from the energy bifurcation at η = 1: QM is the dynamics of non-matter; GR is the geometry of matter. No "quantization of gravity" is required. DEEPENING-7: Emergent Minkowski spacetime (Space v3.3 §5, Time v3.2 §3.4) is constitutionally registered as QM's constitutional stage—not the background in which QM operates, but the symmetry that emerges at the optimal cooperative capacity point. DEEPENING-8: The quantum-to-classical crossover is governed by three independent constitutional mechanisms (decoherence via meltdown channel, force attenuation via encapsulation depth, and jamming via constraint density), of which decoherence and force attenuation are fully developed in v3.1. DEEPENING-9: Quantum information is constitutionally distinguished as transient information (non-matter, no constraint boundary, no maintenance power, no inertial mass), to be contrasted with constraint-grounded information (matter, persistent, E = mc² > 0). DEEPENING-10: The constitutional responses to twenty-six major problems in quantum mechanics are systematically registered, spanning CLOSED-in-EET (QM-GR co-origination, wave-particle duality, QM ↔ Measurement duality), STANDARD (measurement problem constitutionally located, two-channel decoherence, emergent Minkowski spacetime), WORKING HYPOTHESIS (mass as coarse coherence proxy, quantum Darwinism reformulated as blind pump), and CONJECTURE (AdS/CFT correspondence, CDT/MERA emergence). The document is organized as follows. Part I establishes the constitutional foundations, including the Matter/Non-Matter constitutional chain, Barrier Asymmetry conditionalized, and the QFT vs. EET ontological incommensurability. Part II defines QM as non-matter dynamics, establishes the wavefunction as the complex amplitude of non-matter propagation (with systematic comparison to all major QM interpretations), and delineates the constitutional domain boundaries. Part III provides the complete companion ontology interface system, synchronized through June 2026. Part IV-A presents the mathematical foundations, including the Schrödinger equation dual-path derivation and the constraint network path integral. Part IV-B develops quantum states and dynamics, with entanglement re-expressed as shared constraint boundary topology. Part IV-C provides the measurement framework—the non-matter → matter constitutional transition, five-channel measurement, and responses to Frauchiger-Renner, Leggett-Garg, and indefinite causal order. Part IV-D presents the unified two-channel decoherence model and the quantum-to-classical crossover governance with the L_branch concept. Part IV-E treats the vacuum as the N=0 ground state. Part V covers cross-scale instantiation. Part VI provides nine falsifiable predictions. Part VII lists eleven constitutional open problems. Part VIII systematically registers EET constitutional responses to twenty-six major problems in quantum mechanics. Part IX registers the academic priority of forty-eight constitutional claims. Quantum mechanics is the dynamics of the non-material substrate at its optimal operating point. Measurement is the constitutional transition from non-matter to matter. The Schrödinger equation is the deterministic law of non-matter propagation. The Born rule is the statistical law of the non-matter/matter interface. Together, they constitute the complete constitutional framework of quantum mechanics in EET. Keywords: Non-matter dynamics; matter/non-matter distinction; constraint network; coherent free-state propagation; measurement as constitutional transition; two-channel decoherence; quantum-to-classical crossover; encapsulation-depth refinement; Born rule as interface statistics; η-generalized Lindblad equation; emergent Minkowski spacetime; line graph duality; constitutional ontology of quantum mechanics; Energy-Efficiency Theory.
