This paper is the fourth in the XLG Medium Quantum Theory (XLG-MQT) series. It presents the medium interpretation of key quantum phenomena, including double-slit interference, quantum tunneling, the uncertainty principle, Bell-type correlations, and orbital precession. All phenomena are derived from the medium dynamics of the KuiQuark Sea. Photons are treated as density perturbations of the medium. Interference arises from linear superposition of perturbations. Tunneling is exponential attenuation of perturbation amplitude through a high-pressure barrier. The uncertainty principle is shown to be a measurement limit imposed by intrinsic medium fluctuations. Bell-type correlations are explained by continuous medium coupling, not by nonlocal action. Orbital precession is derived from the nonlinear density gradient of the KuiQuark Sea. No probability waves, wavefunction collapse, or nonlocal assumptions are introduced.

For over a century, quantum mechanics has been built upon four core intrinsic assumptions: wave-particle duality, microscopic uncertainty, quantum probability, and nonlocal entanglement. These four assumptions have shaped the modern worldview, holding that the microscopic world is inherently ambiguous, discontinuous, nonlocal, and probabilistic. However, this framework has always suffered from a fatal defect: it can fit experimental results but cannot provide a deterministic causal mechanism, and many core phenomena remain logically paradoxical. Based on the XLG cosmological elastic KuiQuark Sea medium and the helical motion of microscopic particles, this paper adopts the same unified physical rules and calibrated constants established in Papers XI and XII of this series. Without introducing new assumptions, fitting data, or invoking relativistic or quantum axioms, we complete a full representational reconstruction of quantum mechanics. We systematically demonstrate that all quantum phenomena are not fundamental properties of the universe, but arise from three classical mechanisms: elastic fluctuations of the KuiQuark Sea, the intrinsic helical trajectories of microscopic particles, and the geometric limitations of observational measurements. This paper deconstructs and reconstructs wave-particle duality, the Heisenberg uncertainty principle, quantum tunneling, quantum entanglement, interference and diffraction, the ultraviolet cutoff of blackbody radiation, magneto-optical effects, spectral broadening, and redshift mechanisms. All quantum phenomena are reduced to local, causal, classical, and precisely describable medium dynamics and geometric mechanics. The ultimate conclusion is that the universe is a strictly deterministic classical medium system at its foundation. Quantum mechanics is a representational approximate theory formed by the superposition of human observational scale limitations and medium effects.
This paper is the first in the XLG Medium Quantum Theory (XLG-MQT) series. It establishes the foundational axioms, unified symbol system, and core governing equations of a deterministic microphysical framework derived entirely from XLG ECC Cosmology. All physical quantities are defined on the basis of three real entities: KuiQuark, KuiQuark Sea, and ECC-Tauon. The framework abandons probability waves, superposition, collapse, and virtual particles. Microscopic interactions, nuclear equilibrium, molecular bonding, and photonic phenomena are uniformly interpreted via the pressure dynamics of the KuiQuark Sea. This paper presents the complete axiom system, global constant table, and the first three conservation equations (continuity, momentum, and energy) that form the mathematical backbone of XLG-MQT. No phenomenological modifications or probabilistic assumptions are introduced.
Current interpretations of quantum entanglement rely on wavefunction superposition, measurement collapse, and nonlocal correlation assumptions, lacking a physical, visualizable medium description. This paper presents a unified mechanism for entanglement generation, Bell-inequality violations, and decoherence based on the KuiQuark Sea superfluid medium model, the intrinsic helical topology of photons, and the missing-tooth noise effect. We demonstrate that ordinary light sources and entangled photon pairs share an identical underlying medium excitation mechanism, differing only in vortex splitting mode and angular momentum distribution. The observed violation of Bell inequalities (S = 2√2) is interpreted not as evidence for nonlocal action, but as a statistical consequence of continuous random phase perturbations from freely distributed KuiQuark units throughout space — a globally distributed, but locally causal, medium effect. The 2π periodicity of photon helical phase implies that detectors retain only the reduced phase modulo 2π, automatically discarding integer multiples of 2π. The Bell bound is therefore determined solely by the 45° orthogonal measurement geometry. This model avoids the standard hidden-variable assumptions, unifies entanglement generation, correlation maxima, decoherence decay, and medium-dependent transmission differences, without introducing ad hoc hypotheses. It is fully compatible with the photon helical Xu ratio, the missing-tooth probability mechanism, and the underlying fluid dynamics of the microscopic medium.
Traditional quantum mechanics interprets double-slit interference, delayed-choice experiment, quantum eraser experiment, and quantum Zeno effect as fundamental counter-intuitive characteristics of microscopic quantum systems. The conventional framework relies on wave-particle duality, abstract wavefunction collapse, observer-dependent quantum state switching, and information-dominated physical behavior. This paper abandons the traditional assumption of empty vacuum and wave-particle duality. Based on the discrete, elastic, compressible KuiQuark sea medium model, we provide a fully classical, deterministic, mechanical unification of the four core quantum interference phenomena. All quantum paradoxes are eliminated completely. The so-called quantum wave behavior is not an intrinsic property of microscopic particles, but a macroscopic statistical effect induced by particle-excited medium secondary waves and medium ordered structures in vacuum. We further classify two independent physical mechanisms of interference: multi-photon strong-light interference originates from the superposition of helical trajectories of real photon spherical shell clusters, while single-electron sequential interference originates purely from the coherent superposition of KuiQuark medium secondary waves. The delayed-choice effect contains no retro-causality; it only destroys the existing ordered medium channel field after the particle has passed the slit. The quantum eraser effect is a precise mechanical reverse compensation of medium deformation, realizing reversible recovery of medium coherence. The quantum Zeno effect is a dual mechanical locking mechanism: continuous high-frequency detection disrupts balanced medium distribution and forms large-scale reverse medium impact force, which counteracts the forward kinetic energy of particles and freezes microscopic evolution. This study fundamentally eliminates the non-classical hypothesis of traditional quantum mechanics and provides a new deterministic medium-based physical foundation for microscopic interference and quantum observation effects.
We present XLG-MQT, a complete first-principles framework for quantum phenomena derived from the hydrodynamic dynamics of the KuiQuark Sea — a rigid, elastic, compressible medium filling all cosmic space. All quantum effects are shown to be emergent representational phenomena arising from linear weak perturbations, slowly-varying envelope approximation, non-relativistic limit, and coarse-grained averaging of the underlying medium. The framework introduces Xu's Quartet: four canonical equations governing photon helical geometry, medium stability screening, intrinsic photon rotational inertia, and a geometric-priority dual photoelectric criterion. All core constants are derived analytically from KuiQuark microparameters without empirical fitting. We provide a complete step-by-step reduction from the KuiQuark fluid equations to the standard time-dependent Schrödinger equation, with explicit constant matching, physical approximation boundaries, and failure conditions. A unified three-stage atomic emission model resolves previous narrative ambiguities. Five testable predictions are presented with numerical values, experimental conditions, error budgets, falsification criteria, and explicit comparisons with mainstream quantum mechanical expectations. The framework is self-contained, internally consistent, falsifiable, and covers all core quantum phenomena. Quantum mechanics is shown to be not a fundamental theory but a coarse-grained approximation of KuiQuark Sea hydrodynamics under specific physical limits.
This paper is the fifth and final paper in the XLG Medium Quantum Theory (XLG-MQT) series. It summarizes the testable physical predictions and mathematical corollaries derived from the XLG-MQT framework. The predictions include: light speed variation with medium density, galaxy rotation curves explained by medium compression, cosmic density parameters, spectral redshift from background pressure differences, Bell-type correlation decay through solid barriers, and the modified uncertainty limit. These predictions are quantitative and can be distinguished from the predictions of mainstream quantum mechanics and general relativity. The framework provides a clear basis for experimental falsification.
