The observer problem remains one of the central unresolved questions in the foundations of quantum mechanics. This paper derives the logical structure of observation without assuming an observer, consciousness, measurement, or information as primitive concepts. Starting from the primitive notion of Meaning, the following logical sequence is derived: Meaning → Being → Closure → I₄ → Update → Time → 0 < δ < ∞ → Self-Reference → Observer → Observation → Record → Synchronization → Information. Within this framework, an observer is shown to emerge necessarily from persistent self-referential closure possessing finite residual relation. Observation is interpreted as the generation of persistent internal representations, while measurement is reformulated as synchronization between independent closures. Information is derived as synchronized records supported by an information medium. This logical structure provides a unified reinterpretation of Schrödinger's cat and Wigner's friend. The apparent paradoxes are shown to originate from synchronization between independent observers rather than from consciousness, observer-dependent reality, or wave-function collapse. The paper establishes an ontological hierarchy connecting Meaning, Being, observation, synchronization, and information within the MBC (Meaning-Based Constraint) framework.

This paper reconstructs the concept of observation from first principles rather than treating it as a primitive notion. Starting from the existence of meaning, a unique structural dependency chain is derived: Meaning → Being → Subject → Other → Distinction → Comparison → Order → Time → Update → Self-Reference → Observation → Record → Synchronization → Information Each stage is proven to be a necessary prerequisite for every subsequent stage. Within this framework, observation is shown not to create or determine reality. Instead, reality must already exist before observation becomes possible. Observation is defined as a structural operation performed on an already existing reality. The paper further applies this structural derivation to the observer problem, Schrödinger's cat, Wigner's friend, and the double-slit experiment. It argues that the disappearance of interference should be interpreted as the consequence of changes in physical interaction together with the subsequent processes of recording and synchronization, rather than evidence that observation itself creates or modifies reality. This work provides a mathematical reconstruction of observation prior to information and proposes a unified structural framework for interpreting quantum measurement from more fundamental principles.
This paper presents a unified mathematical reconstruction of three fundamental quantum observer problems: Schrödinger's cat, Wigner's friend, and the double-slit experiment. The proposed framework distinguishes six logically different concepts: Existence Physical Interaction Internal Representation Record Synchronization Information Within this framework, physical reality exists independently of observation. Observation is defined as the formation of a persistent internal representation, while synchronization is the sharing of equivalent records between independent physical closures. Consequently, observation does not generate reality; it synchronizes an observer with a reality that already exists. Using this common structure, Schrödinger's cat and Wigner's friend are reconstructed without requiring multiple physical realities or observer-dependent existence. The same synchronization framework is then extended to the double-slit experiment. The paper proposes that when synchronization with electron A is absent, the electron continues to exist and evolve physically, while its propagated field can locally drive a material response at the screen. A real local-dynamics simulation with a fixed apparatus, persistent medium, cumulative screen recording, finite propagation, dissipation, and thermal fluctuations is presented. The simulation produces a stable multi-peak spatial structure without imposing an interference formula or a target fringe pattern. The work provides a unified logical framework connecting observation, synchronization, and quantum measurement, while remaining explicit about the distinction between numerical consistency and experimental verification.
The quantum measurement problem is traditionally framed as a conflict between unitary dynamics and the emergence of definite outcomes. A wide range of quantum paradoxes—including Schrödinger’s Cat, Wigner’s Friend, Bell nonlocality, delayed-choice experiments, and the Quantum Zeno effect—are commonly interpreted as manifestations of this conflict. This paper argues that these paradoxes share a common origin: the assumption that quantum states represent observer-independent physical reality. Building on an Observer-First Interpretation (OFI), quantum states are instead treated as observer-relative informational constructs constrained by evidence accessibility and record stability. Within this unified framework, definite outcomes, nonlocal correlations, temporal ordering, and measurement-induced stabilization emerge consistently without modifying quantum mechanics or introducing additional dynamics. The quantum measurement problem is thus reformulated as an informational consistency condition rather than a physical inconsistency.
Schrodinger's cat is traditionally presented as a paradox highlighting the tension between quantum superposition and classical observation. Standard interpretations invoke either a fundamental wavefunction collapse, ontological branching of universes, or subjective Bayesian updating. In this paper, we propose a reinterpretation grounded in the Informational Observer Framework, according to which the paradox does not originate from an ontological superposition of macroscopic states, but from an unresolved informational configuration at the observer level. The cat itself is never simultaneously alive and dead; rather, the observer remains in a state of informational compression prior to interaction. Within this framework, wavefunction collapse is reinterpreted as an observer-level informational phase transition, not as a fundamental physical discontinuity. This approach preserves macroscopic realism, avoids ontological inflation, and reframes the measurement problem as an emergent informational phenomenon.
This paper offers a comprehensive analysis of Wigner’s Friend paradox (1961), a foundational thought experiment in quantum mechanics that highlights the tension between the internal perspective of a measuring observer (who experiences a definite outcome) and the external perspective of a super-observer who treats the entire laboratory as a quantum system in superposition. It traces the historical lineage from Schrödinger’s cat and von Neumann’s measurement theory, provides a formal mathematical description of the state evolution and logical structure of the paradox, examines implications for major interpretations of quantum mechanics (Copenhagen, Everettian many-worlds, QBism, relational quantum mechanics, and objective collapse theories), and discusses modern extensions such as the Frauchiger–Renner paradox. The work explores profound philosophical and epistemological consequences for the nature of observation, objectivity, intersubjectivity, and the role of consciousness in quantum theory (2026).
Quantum mechanics lacks a physical definition of measurement, observer, probability, and experienced time. These notions are instead treated as primitive or interpretation-dependent, leading to persistent foundational problems including the measurement problem, the origin of the Born rule, observer disagreement in Wigner’s Friend scenarios, the arrow of time, and apparent information loss in black hole evaporation. In this work, we show that these problems share a single missing ingredient: the absence of an operational definition of observers as bounded physical systems. We define observers as physically realizable systems capable of forming irreversible internal records under unitary dynamics. Measurement is identified with record formation, probability with record redundancy, experienced time with record accumulation, and irreversibility with computational inaccessibility rather than non-unitarity. Using decoherence and quantum Darwinism, we show that the number of accessible, decoherence-stable records associated with an outcome scales with the squared amplitude, yielding the Born rule from record counting without invoking collapse, subjective probability, or additional axioms. Observer-relative paradoxes dissolve once outcome definiteness is indexed to record formation rather than to the global quantum state. Reconstruction of global quantum information is shown to require exponential resources, rendering measurement and black hole evaporation operationally irreversible despite global unitarity. The resulting framework closes quantum mechanics conceptually by eliminating undefined primitives, without modifying its mathematical structure or introducing new dynamical postulates.
