This paper presents a first-principles physical simulation of the double-slit experiment to investigate causal emergence in quantum systems. Unlike traditional approaches that rely on pre-sampled distributions, our simulation generates particle trajectories from fundamental physical laws, incorporating quantum interference potential and decoherence effects. We demonstrate that quantum coherence leads to causal emergence, where macroscopic descriptions contain more information than microscopic ones, as quantified by effective information (EI). The simulation reveals a phase transition at a critical decoherence strength, beyond which causal emergence disappears. Our results provide computational evidence for the theoretical framework of causal emergence in quantum mechanics and highlight the role of observation in altering explanatory power. The methodology avoids data filtering bias by generating trajectories self-consistently from physical principles.

The double-slit experiment has remained one of the most profound and conceptually challenging demonstrations in physics. While the mathematical framework of Quantum Mechanics - superposition, wave function, and state collapse - accurately predicts outcomes, it fails to provide a clear causal description of how potential quantum states transform into actual, registered events. This paper presents the Event-Chain Model, a new conceptual framework that represents every quantum process as a causal sequence of connected physical events. Each event reflects an irreversible registration, transforming quantum potentials into factual reality. The model introduces three core components: the Potential Pattern, the Irreversible Event, and the Event Chain that constitutes reality itself. Using this framework, the paper explains interference, decoherence, quantum erasure, and the EPR-eraser experiments without invoking many-worlds or retrocausality. Superposition is defined as a Potential Pattern - a structured map of possibilities - while collapse is redefined as a natural, physical registration process that generates an event in the chain of reality. Interference patterns thus emerge not as physical waves but as cumulative records of uncollapsed potentials. The Event-Chain Model preserves all results of Quantum Mechanics while adding a transparent causal layer, linking mathematical formalism with physical reality. It provides a unified interpretation of how potential, event, and actuality co-exist and evolve within a consistent quantum framework.
The double-slit experiment provides insights into quantum mechanics and sheds light on fundamental contradictions with classical physics, which, although predicting independent trajectories by simple random addition, reveals interference patterns even when only one particle is emitted at a time, providing direct evidence for effects of wave-particle duality and quantum superposition. Furthermore, we explore why thematic coherence and overlap in this study are essential elements of quantum computer design. Mechanisms such as phase interference (defined by the Deutsch algorithm) demonstrate the computational power provided by quantum effects. In other words, double-slit learning is not just a theoretical concept, but also a set of ideas and techniques that combine the theory of advanced quantum technology.
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.
The double-slit interference experiment serves as a fundamental experiment in quantum mechanics. Core theories including wave-particle duality, quantum superposition and measurement collapse are established on the basis of this phenomenon. The mainstream Copenhagen interpretation and Bohmian pilot-wave theory rely heavily on mathematical statistical fitting to interpret experimental outcomes, yet they fail to reveal the real physical evolution mechanism of photons at the microscale. Moreover, they inherently suffer from symmetry breaking, causal discontinuity and logical inconsistency. The symmetry-breaking analogy widely adopted in academic circles contains dimensional mismatch and conceptual substitution, representing a cognitive bias that places mathematical tools above physical mechanisms. Based on the symmetry principle of classical physics and the rule of continuous causal evolution, this paper systematically identifies the core defects of mainstream quantum interpretations and points out the paradigm limitation of quantum mechanics that prioritizes mathematical fitting over physical ontology. A spatial particle resonance propagation model is proposed. This model explains that photons are essentially the resonance manifestation of space particles. When resonance passes through double slits, the resonance body splits symmetrically, and then recombines after passing through the slits to form interference. Measurement will break the symmetry of resonance, resulting in the disappearance of interference fringes. This model maintains continuous causality and geometric symmetry, and provides a new physical mechanism explanation for quantum uncertainty and measurement effects in double-slit experiments.
This paper presents an environment-first account of the double-slit experiment grounded in Boltzmann-Landauer thermodynamics. It argues that classicality does not arise from particle dynamics, observation, or probability, but from irreversible registration executed by an entropy-bearing environment capable of enforcing exclusion at a minimum thermodynamic cost. Quantum amplitudes and Hilbert space are left unchanged and are treated as representations of admissible structure beyond thermodynamic solvency. Interference persists whenever energy-carrying processes remain unregistered. The disappearance of interference is attributed to environmental registration, not to collapse, observation, or decoherence as a causal mechanism. Decoherence and probability are interpreted as downstream statistical descriptions that apply after irreversible registration has occurred. The paper is diagnostic rather than constructive: it identifies a physical precondition for classical outcomes without proposing new dynamics or modifying quantum mechanics. The analysis reframes the double-slit experiment as a problem of environmental enforceability rather than probabilistic paradox, situating classical facts within thermodynamic constraint rather than epistemic update.
The double slit experiment provides a classic example of both interference and the effect of observation in quantum physics. When particles are sent individually through a pair of slits, a wave-like interference pattern develops, but no such interference is found when one observes which "path" the particles take. We present a model of interference, dephasing, and measurement-induced decoherence in a one-dimensional version of the double-slit experiment. Using this model, we demonstrate how the loss of interference in the system is correlated with the information gain by the measuring apparatus/observer. In doing so, we give a modern account of measurement in this paradigmatic example of quantum physics that is accessible to students taking quantum mechanics at the graduate or senior undergraduate levels.
