Layered Operational Realism (LOR) is introduced not as a replacement for quantum mechanics, but as a methodological framework for separating operational predictions from interpretational claims in mesoscopic quantum experiments and tabletop gravity proposals. The framework distinguishes three layers: Layer I contains the empirically testable formalism of quantum mechanics, including unitary evolution, density operators, and Born-rule probabilities; Layer II concerns the emergence of classical objectivity through decoherence, environment-induced superselection, and Quantum Darwinism; Layer III contains optional ontological overlays such as Copenhagen, Everettian, QBist, relational, or collapse-based interpretations. Many contemporary disputes in mesoscopic quantum mechanics and gravitational entanglement experiments arise from conflating these layers. LOR does not resolve the measurement problem or provide a new physical law. Instead, it offers a disciplined framework for distinguishing experimentally testable claims from interpretational extrapolation.

Quantum mechanics is empirically extraordinarily successful yet continues to admit a wide range of competing interpretations. While the formalism constrains probabilistic relations between preparation procedures, measurements, and outcomes, it does not uniquely determine the ontology that realises those relations. Interpretations such as Everettian quantum mechanics, Bohmian mechanics, objective collapse theories, relational quantum mechanics, and QBist approaches preserve the predictive structure of the theory while diverging sharply in their metaphysical commitments. At the same time, developments within quantum theory itself weaken the classical ontology of independently existing objects with intrinsic properties. Entanglement, violations of Bell inequalities, and decoherence theory collectively support the view that physical description is fundamentally relational. Structural realism therefore provides a natural interpretive framework, treating the mathematical structure of physical theory as ontologically primary. However, structural realism alone leaves open the question of instantiation: how relational organisation becomes concrete as a determinate world.This paper develops Experiential Structural Ontology (ESO) as a non-interventionist interpretation of quantum mechanics that addresses this problem. ESO retains the relational ontology suggested by quantum theory while proposing that relational constraint organisation is enacted as manifestation within a fundamental experiential field. On this interpretation, the wavefunction represents relational constraint architecture governing transitions within this field, measurement corresponds to the stabilisation of particular regimes within that structure, and decoherence explains the emergence of classical stability without invoking collapse dynamics or ontological branching.
The quantum measurement problem remains a central unresolved issue in theoretical physics, arising from the incompatibility between unitary quantum dynamics and the emergence of definite measurement outcomes. Closely related is the question of the physical status of the wavefunction within contemporary quantum theory. This review critically surveys leading approaches to the measurement problem, focusing on their formal consistency, physical assumptions, and empirical implications. We examine the standard measurement framework, the role of environment-induced decoherence and quantum Darwinism, and the restrictions imposed by no-go theorems such as Bell, Kochen–Specker, and Pusey–Barrett–Rudolph. Interpretations including Everettian many-worlds, Bohmian mechanics, spontaneous collapse models, relational quantum mechanics, QBist approaches, and Copenhagen-type frameworks are assessed in terms of their ability to account for classical definiteness without sacrificing empirical adequacy. We also review experimental efforts probing macroscopic superpositions and collapse dynamics. The analysis indicates that, despite its predictive success, quantum theory lacks a complete physical account of outcome selection. This suggests that the measurement problem reflects a fundamental structural limitation of current theory, motivating either new physical principles or a redefinition of the wavefunction’s ontological role.
The Layered Reality Theory (LRT) proposes that physical reality consists of distinct ontological layers—quantum, classical, cosmic—each governed by its own complete set of relative truths. These layers are autonomous, not emergent or perspectival. They coexist through an invariant condition called Absolute Truth, constrained by the Balance Principle: no system can fully instantiate two layers' truths simultaneously. LRT is axiomatic, falsifiable, and reframes the plurality of physical laws as a structural feature of reality
We develop a four-layer operational architecture for quantum measurement andclassical emergence, consisting of reversible dynamics (U), decoherence and pointerselection (E), instrumental measurement updates (I), and redundant record formation(R). The architecture is expressed entirely in terms of completely positivetrace-preserving (CPTP) maps on Hilbert spaces and is compatible with standardquantum mechanics in all major interpretations.We show how decoherence, quantum Darwinism, multi-observer consistency,macro-objectification, and the Born rule arise as interlocking constraints withinthis framework. In particular, we derive the Born rule as the unique probabilityassignment at the instrumental layer compatible with positivity, normalization,additivity under coarse-graining, noncontextuality for effects, covariance underreversible dynamics, and continuity.We illustrate the entropy flow and redundancy structure using explicit two- andthree-qubit examples with complete calculations, and provide a tensor-network representationof the full observer pipeline. The architecture is shown to be the quantummechanical foundation for a programme of classical shadow stability analysis, inwhich projecting the UEIR structure onto Boolean configuration spaces yields exactstability results for complex systems including conflict resolution, AI alignment, andbiological morphogenesis [Sikiru, 2026a,b,c]. The result is an interpretation-neutral,operationally complete account of how classical reality emerges from quantumstructure.
The Copenhagen interpretation's "wave function collapse" postulate has resisted unified physical explanation for over a century. This article proposes an alternative ontological framework: measurement outcomes do not result from instantaneous collapse, but from realization—the emergence of actuality from potentiality through capacity-dependent thresholds. We posit that consciousness constitutes the fundamental source of potentiality, while observer capacity (quantified via mutual information, distinguishability, or decoherence rates) determines whether potentiality actualizes into observable reality. This framework is formalized via soft-threshold sigmoid activation operators R(C,T) = 1/(1+exp(-k(C-T))), projection operators on Hilbert space, and organizational-level resonance. We address three critical objections: (1) panpsychism is avoided through organization-dependent ontological realism; (2) decoherence is reinterpreted as resonance between organizational levels rather than passive information leakage; (3) six falsifiable experimental predictions are presented, spanning double-slit variable-capacity detection, quantum erasers, Stern-Gerlach weakening, infant neural dimensionality growth, sensory threshold development, and REM sleep correlation with learning. Mathematical consistency with Born rule and Hilbert space formalism is established via normalization conditions and unitary operation proofs. The model reconciles quantum mechanics, consciousness studies, developmental neuroscience, and sleep physiology within a single ontological framework, offering testable alternatives to Copenhagen, many-worlds, pilot-wave, and objective-collapse interpretations.
This paper introduces the Quantum Reality Interface Layer (QRIL), a theoretical framework proposing a physical interface layer mediating interactions between the quantum realm and classical reality. The QRIL aims to bridge the quantum-classical divide, a long-standing challenge in physics. The core concept involves the existence of a layer, denoted as [I_R], that facilitates the translation and interpretation of quantum phenomena within a classical context, and vice versa. This framework offers a potential pathway towards understanding and manipulating quantum systems while maintaining coherence with observed classical reality. The proposed QRIL has significant potential for resolving fundamental questions regarding quantum measurement, decoherence, and the nature of reality itself. The exploration of macro-quantum experiments utilizing this interface layer is also suggested as a key area for future investigation. ---
