Reconstruction of Schrödinger's Cat in Many Worlds 6; Symplectic Duality in Quantum Information Geometry and the Emergent Theory of Many-Worlds Measures
This paper constructs a new framework for the many-worlds interpretation thatintegrates symplectic geometry, quantum information geometry, and optimal transport theory. The central thesis is that world branches are not static splits in Hilbertspace, but rather a Lagrangian submanifold fibration process on a symplectic manifold driven by decoherence. We prove that the Born rule for the squared magnitudeof wave function amplitudes arises from a strict duality between symplectic volume conservation and the measure transformation induced by the quantum Fishermetric. An optimal transport cost functional between worlds is introduced as adynamical criterion for branch reality: a corresponding branch can support a stable information-recording structure if and only if the transport cost is lower thana critical threshold determined by the spectral gap. This framework transformsthe traditional measure problem of the many-worlds interpretation into a computable geometric optimization problem and achieves an explicit construction ofself-consistent observer conditions within the string theory landscape. The theorypredicts observable geometric phase effects in superconducting quantum simulators,and on cosmological scales, it corresponds to non-Gaussian deviations in primordialdensity perturbations. This work provides a complete mathematical implementation for the many-worlds interpretation, from ontology to phenomenology.

This paper constructs a logically self-consistent emergent structural frameworkfor the Many-Worlds Interpretation (MWI) based on decoherence theory, quantum information geometry, and self-referential dynamics. Within this framework,a ”world” is rigorously defined as a quasi-classical branch formed in Hilbert spacethrough environmental decoherence and information-geometric boundaries. Its independence is quantitatively characterized by the branch separation degree Dab defined by the quantum relative entropy between branches. When Dab exceeds a critical value Dc determined jointly by the energy scale of environmental fluctuationsand the decoherence time, the branches separate irreversibly in the informationgeometric sense, constituting independent ”worlds”. Furthermore, by introducingthe concept of a self-consistent observer, this paper demonstrates the dynamic selection mechanism of cosmological laws within the string theory landscape: only thosevacuum branches that can support self-consistent observers (satisfying conditionssuch as the memory decoherence time being much greater than the cognitive operation time) have their wavefunction weights effectively preserved during evolution,thereby acquiring physical reality. Finally, combining Zurek’s envariance argumentwith the requirement of observer memory stability, we show that the Born ruleP(i) = |⟨i|ψ⟩|2 is not an additional assumption but a necessary consequence forthe stable existence of self-consistent observers. This framework provides an operational mathematical foundation for the many-worlds interpretation, transforms theanthropic principle into a dynamic selection problem, and offers an explanation forthe origin of probability based on quantum information principles.
This paper proposes a quantum measurement framework based on structuralstability theory, aiming to resolve the logical dilemma of the quantum–classicaltransition in Schrödinger’s cat paradox. Traditional quantum mechanics relies onexternal mechanisms such as “observer introduction” or “decoherence” to explainmacroscopic reality, leading to vague ontological commitments. We argue that thefundamental reason macroscopic quantum states cannot maintain coherent superpositions lies in the self-organizing critical behavior constrained by the system’sinternal structural stability. The core mechanism is: when a quantum system couples with a classical measuring device, its Hilbert space representation is forced toproject from a high-dimensional unitary representation onto a low-dimensional classical representation, a process driven by the extremization of a structural stabilityfunctional, not by external observation. We rigorously prove that when the system’sstructural information density exceeds a critical threshold, the quantum superposition state cannot satisfy self-consistency constraints mathematically; the systemmust select a classical eigenstate through an “algebraic filtration” mechanism. Thetheory yields three testable predictions: (1) a microscopic entropy production pulseat the moment of coupling between the measuring device and the quantum system,of order 10−21 J/K; (2) a deviation of the quantum Zeno suppression factor fromstandard quantum mechanical predictions on microsecond scales; (3) a scaling-lawdivergence of the decoherence time of macroscopic superpositions at critical parameters. These effects can be tested in coupled superconductor qubit–mechanicalresonator systems. The framework does not modify unitary evolution, does not relyon many-worlds assumptions, and does not introduce collapse postulates; instead,it transforms the measurement problem into a question of compatibility betweenquantum information structure and geometric–topological constraints.
Based on the mathematical framework established in the Observer Geometryseries (A-I), this paper proposes a novel structural resolution to Schrödinger’s catparadox and the many-worlds interpretation. By internalizing the observer as aself-referential subsystem of noncommutative algebras, we prove that the core ofthe quantum measurement problem is not ”how the wave function collapses” or”how worlds branch”, but rather the self-referential rupture and repair of the observer algebra structure at the micro-macro interface. This paper unifies six existing theories—Dynamic Time Algebra, Post-Markovian Paradigm, Temporal LayerCausal Evolution, Chronogroup Framework, Time Fiber Category, and Origin ofOrder—and demonstrates that they are all effective descriptions of observer geometry under different projections. We derive three testable predictions: logarithmicoscillatory patterns in CMB non-Gaussianity, topologically chiral currents without external fields in mesoscopic systems, and magic number resonance structuresin high-energy colliders. This framework elevates the many-worlds interpretationfrom ”metaphysics of parallel universes” to ”geometric realization of self-referentialalgebras”, providing a mathematically self-consistent and experimentally testableunified solution to the foundational problems of quantum mechanics.
The many-worlds interpretation holds an important position in foundationalstudies of quantum mechanics due to its ontological parsimony—adhering to theuniversality of the wave function and unitary evolution. However, this interpretation has long faced core challenges such as the fuzzy mathematical definition of”world branches” and the origin of probability. Within the framework of a ”faileduniverse,” this paper re-examines the generation conditions and existence formsof many-worlds structure. By introducing topological constraint phase transitionsand self-referential reconstruction dynamics, we prove that when the universe is in a”failed phase” caused by insufficient logical depth, the global many-worlds description collapses, but its topological order parameter—the second Chern number—localizes in a modularized discrete form within causal fragments. The many-worldsdo not disappear but exist in a fragmented, modalized manner; the quantum measurement process is reconstructed in this picture as a topological transition of theobserver on the boundaries of causal fragments, rather than instantaneous wavefunction collapse or global world splitting. This framework unifies quantum measurement, spacetime emergence, and cosmological observations into a self-consistenttheoretical system, and derives three experimentally distinguishable predictions:non-Gaussianity of the cosmic microwave background radiation, the logical noisespectrum of primordial gravitational waves, and a detectable discrete chiral currentin mesoscopic circuits.
This paper systematically elaborates on the structural interpretations of sixemerging mathematical physics frameworks for Everett’s many-worlds interpretation, including the branching structure of dynamic time algebra, the logical parallelism of the post-Markovian paradigm, the historical bifurcation of temporal layercausal evolution, the representation splitting of the time group framework, the section bundling of chronological fiber categories, and the stability selection in theorigin of order theory. These theories, from different perspectives, demonstratethe global unitarity of quantum state evolution, reinterpreting ”world splitting”as representation branching, logical parallelism, or fiber bundling on mathematical structures, thereby providing a mathematical foundation for the many-worldsinterpretation independent of philosophical assumptions. By comparing the coremechanisms, mathematical structures, and physical predictions of each theory, thispaper proposes a unified view: the many-worlds is not ”splitting” but a naturalresult of structural degeneration, and all branches are mathematically equal andco-existent. At the same time, this paper discusses feasible paths for experimentalverification and introduces the category of potential worlds to unify the six theories,clarifying how the condition of observer self-consistency leads to the Born rule.
This mini-monograph proposes a new variational and information-geometric framework for understanding the quantum measurement problem, with particular emphasis on the unresolved problem of outcome selection. While decoherence theory explains the suppression of interference and the emergence of stable pointer bases, it does not by itself explain why one definite outcome is realized rather than another. This work argues that the missing element is not simply an additional dynamical mechanism, but a structural principle of selection. The central thesis is that quantum measurement may be understood as a process of entropic channel selection within a structured space of admissible outcomes. Drawing on Schrödinger bridge theory, entropy-regularized optimal transport, stochastic path-space variational principles, concentration of measure, and large deviation theory, the monograph develops a framework in which collapse-like definiteness emerges through constrained probabilistic evolution. Measurement is thereby reinterpreted not as an arbitrary interruption of unitary dynamics, but as a threshold phenomenon in the geometry of information. The work introduces an informational configuration space of possible resolution channels, defines an entropic action functional over stochastic paths, and proposes a channel-selection principle based on entropy-minimizing interpolation. It further examines the relation between Schrödinger bridges and optimal transport, explores the zero-noise limit, connects the framework to path-integral intuition, and develops explicit models of Gaussian bridge dynamics and two-channel selection. The emergence of classicality is treated through exponential concentration, threshold amplification, and phase-transition-like stabilization in high-dimensional systems. The monograph does not claim to replace standard quantum mechanics. Rather, it seeks to clarify how definite outcomes might arise from variational organization within probability itself, while remaining compatible with reduced quantum dynamics, decoherence, and open-system evolution. It is intended as a conceptual and mathematical foundation for further work at the intersection of quantum foundations, stochastic processes, information geometry, and the theory of emergent classicality.
