We introduce the Quantum Consensus Principle (QCP), a first-principles framework that provides a dynamical derivation of quantum measurement within standard open-system quantum mechanics, without modifying the Schrödinger equation. By treating the system–apparatus–environment complex as an open quantum system, QCP derives measurement outcomes from a thermodynamic selection process governed by large-deviation dynamics. Central to the theory is a calibrated selection potential built from two canonical apparatus statistics, the redundancy rate and the noise susceptibility, defined in Bogoliubov–Kubo–Mori information geometry and linked to microscopic Hamiltonian parameters via Green–Kubo transport coefficients. Within the admissible class specified in the companion Supplement, the effective selector is unique up to affine gauge and takes a linear form in the canonical scores. In the Markovian pointer-preserving regime, the conditioned state process forms a Hellinger-type supermartingale and converges almost surely to unique pointer states. The Born rule is recovered as the exact trajectory-frequency law of the neutral instrument, while non-neutral calibrated instruments generate controlled POVM-level deviations. QCP further predicts a characteristic non-monotonic scaling of collapse timescales, providing a concrete route to experimental falsification. This work bridges quantum information theory and non-equilibrium thermodynamics by identifying measurement as a consensus phenomenon in macroscopic systems. Taken together, the main paper, Supplement, and companion notes establish the full physical and mathematical architecture of QCP.Unlike approaches that treat measurement primarily at the level of interpretation, QCP advances a unified operational program in which single-outcome selection, neutral-instrument Born recovery, apparatus-dependent deviations, and calibration from microscopic detector physics arise within one framework. Its significance therefore lies not only in proposing a collapse architecture, but in turning foundational claims into quantitative questions about response matrices, transport coefficients, and experimentally testable timescales. In this sense, QCP is designed to move the measurement problem from the level of competing narratives to the level of calibrated dynamical law.

We introduce the Quantum Consensus Principle (QCP), a first-principles framework that provides a purely dynamical derivation of the quantum measurement process without modifying the Schrödinger equation. By treating the apparatus–environment complex as an open quantum system, we show that measurement outcomes emerge from a thermodynamic selection process governed by large-deviation dynamics. Central to the theory is the derivation of a universal selection potential, Φᵢ, which is uniquely determined by the BKM information geometry of the thermal environment and linked to microscopic Hamiltonian parameters via Green–Kubo relations. We rigorously demonstrate that the conditioned system state follows a Hellinger-contractive supermartingale, converging almost surely to unique pointer states. Unlike standard postulates, QCP derives the Born rule as a specific neutrality limit and predicts measurable, apparatus-dependent deviations for non-ideal observers. Furthermore, the theory establishes a characteristic non-monotonic scaling of collapse timescales, providing a clear path for experimental falsification. This work bridges the gap between quantum information theory and non-equilibrium thermodynamics, identifying measurement as a fundamental consensus phenomenon in macroscopic systems.

This record presents Execution-Based Quantum Theory of Measurement: A Thermodynamic Completion Framework, a theoretical framework addressing the unresolved question of how and when quantum possibilities become executed physical outcomes. Standard quantum mechanics accurately predicts probability distributions but does not specify the physical conditions under which a potential outcome becomes an irreversible fact. This work proposes a completion rule, not an interpretation, grounded in continuous time evolution, irreversible dissipation, and global informational consistency. The framework introduces: Execution as a time-extended, physical process distinct from decoherence A minimum irreversible energy dissipation condition required for outcome realization A measurable execution timescale (τₑₓₑc), distinct from decoherence time A Wait State regime where interference may be suppressed while execution remains incomplete Conditional, sequential extension of reality through successive executions, without invoking observer causation, instantaneous collapse, or parallel universes The theory preserves all established first principles, including unitary quantum dynamics prior to execution, thermodynamics, and a single continuous spacetime. Observers and measurements are treated as physical record-holders that arise after execution, not as causal agents. Four falsifiable experimental tests are proposed across independent platforms: Tunable dissipation in superconducting circuit QED Photonic which-path storage with dissipation gating Mesoscopic pointer systems with controlled environmental damping Matter-wave interferometry under adjustable thermal load Each experiment provides explicit scaling laws and failure criteria to test the separation between decoherence and execution. This framework is derived from, but does not redefine, the Resonance Trinity Law (RTL), which serves as the parent substrate-level principle. No experimental validation is claimed in this record; the purpose is to define a clear, testable theoretical structure and safeguard authorship prior to experimental investigation.
Abstract The quantum measurement problem arises from the coexistence of unitary Schr¨odinger evolution with the apparent nonunitary collapse of quantum states during observation. Despite extensive theoretical development, no consensus has been reached on a microscopic physical mechanism for state reduction within standard quantum theory. In this work, we present a complete dynamical theory of quantum measurement in which wavefunction collapse emerges from irreversible information transfer and entropy production in realistic system–detector–environment interactions. Starting from microscopic Hamiltonian models, we derive a stochastic nonlinear evolution equation for conditioned quantum states without introducing additional axioms or phenomenological parameters. We demonstrate that the effective collapse rate is uniquely determined by environmental entropy production and remains well-defined in thermal, non-Markovian, chaotic, and zero-temperature regimes. Using stochastic calculus and martingale theory, we establish the dynamical emergence of the Born probability rule and prove almost-sure convergence of measurement trajectories to definite outcomes. The theory exhibits robust many-body amplification, universal behavior in nonlinear detectors, and mathematical well-posedness in both finite- and infinite-dimensional settings. Compatibility with algebraic quantum field theory, renormalization theory, and stochastic semiclassical gravity is established, ensuring consistency with relativistic and high-energy physics. Extensive numerical simulations confirm analytical predictions, and a comprehensive experimental program is proposed, together with rigorous validation and replication protocols. Logical analysis demonstrates compatibility with Bell nonlocality, resolution of Wigner’s friend and Frauchiger–Renner paradoxes, and compliance with information-theoretic constraints. These results provide a unified physical explanation of quantum measurement as an emergent nonequilibrium process governed by universal thermodynamic and informational principles, integrating state reduction into the standard dynamical framework of physics.
