This work presents a fully analytic and collapse-free explanation for the suppression of interference in the double-slit experiment under measurement. The core idea is a simple probability-conservation rule in which the total amplitude of the system is redistributed between a coherent matter mode and a radiative (detector) mode. This mechanism, referred to as mode-fission, yields a direct scaling relation for the interference term,Iint(t) = pm(t) · Iint(0),showing that visibility decreases in proportion to the remaining coherent fraction of the matter mode.The derivation requires no wave-function collapse, no environment-induced decoherence, and no non-unitary dynamics. It provides a deterministic, physically transparent alternative to traditional interpretations of quantum measurement, and generalizes naturally to Mach–Zehnder interferometers, cavity-QED photon counting, Ramsey fringes, and qubit readout.

The “measurement problem” and the subsequent postulate of instantaneous wave-function collapse remain persistent pedagogical challenges in quantum mechanics. This paper proposes that the apparent paradox of measurement arises from an incomplete idealization of the measuring apparatus as a passive observer, rather than a physical, interacting system. By discarding the unitary state vector formalism during the act of measurement and modeling the detector explicitly as an active noise manifold using the Lindblad master equation, we demonstrate that the suppression of quantum interference is a deterministic, calculable mechanical degradation of phase coherence. Through a numerical simulation of the double-slit experiment, we show that scaling the detector’s stochastic noise rate γD smoothly reproduces the pure unitary interference regime, the weak-measurement partial decoherence regime, and the emergence of classical probability distributions, offering a concrete pedagogical alternative to non-unitary projection postulates.
This paper develops a fully empirical, physics-grounded reinterpretation of the double-slit experiment using the same flux-ledger framework established in Modules A–D of the Zero Infinity Research Program. By expressing quantum interference in terms of probability current density, boundary flux, and environmental decoherence, the work shows that the double-slit phenomenon requires no mysteries, hidden forces, or nonlocal metaphysics. Instead, the interference pattern emerges naturally from: Conservation of probability current, Phase-coherent flux across an open boundary, and Loss of coherence encoded as a measurable entropy-flux term Ψ∞. The analysis re-derives the standard results—interference fringes, collapse under measurement, and decoherence scaling—from first principles while embedding them within the broader conservation trilogy: Φ∞ (boundary energy flux) Ψ∞ (entropy/memory flux) Π∞ (momentum flux) This connects quantum optics to the same flux-driven framework used to model black hole mergers, spacecraft recoil, comet polarization curves, and organic spectral coherence in earlier modules. The paper also integrates cross-disciplinary results from decoherence theory, Bohmian mechanics, optical coherence tomography, and open quantum systems, showing how each maps cleanly onto a boundary-flux formalism. The result is a physically rigorous, mathematically transparent, and conceptually unifying explanation of the double-slit experiment—one that preserves standard quantum mechanics while clarifying how and where interference information is stored, exported, and erased. This work extends the Zero Infinity Program into quantum foundations, offering a synthesis of classical wave mechanics, quantum probability current, thermodynamic export, and information flow across system boundaries.
Over the past several decades, single photon-based path interference in double-slit experiment has been well demonstrated for the particle nature of photons satisfying complementarity theory, where the quantum mechanical interpretation of the single photon interference fringe is given by Born rule for complex amplitudes in measurements. Unlike most conventional methods using entangled photon pairs, here, a classical coherent light source is directly applied for the proof of the same self-interference phenomenon. Instead of double slits, we use a Mach-Zehnder interferometer as usual, where the resulting self-interference fringe of coherent single photons is exactly the same as that of the coherent photon ensemble of the laser, demonstrating that the classical coherence based on the wave nature is rooted in the single photon self-interference. This unexpected result seems to contradict our common understanding of decoherence phenomena caused by multi-wave interference among bandwidth distributed photons in coherence optics.
The double‑slit experiment epitomizes the wave–particle duality of quantum mechanics. In standard treatments, the interference pattern follows from superposition, while measurement of “which path” destroys coherence. The precise mechanism that turns a coherent superposition into a localized detection event remains an open question. We propose an operator‑based model within the open‑quantum‑system framework that describes the entire process through seven effective Lindblad generators: fluctuating diffusion (initial wavepacket spreading), cyclic reset (quantum Zeno effect), spatial‑mode splitting (simultaneous excitation of both slits), free evolution (interference formation), liminal projection (threshold‑activated measurement), irreversible loss (detector inefficiency), and subspace mapping (projection onto a definite detection outcome). Unlike standard quantum mechanics, the model introduces a nonlinear decoherence rate that depends on the spatial spread of the wavefunction, capturing environment back‑action through a feedback‑controlled coupling. This dependence leads to a small but testable reduction of fringe visibility with increasing particle flux or wavepacket width, even in the absence of explicit which‑path measurement. The measurement activation is modeled as a smooth threshold function, giving a sharp transition in detection probability as the system reaches the screen. Analytical expressions for visibility and the critical Zeno frequency are derived, and numerical simulations are presented. The predictions are accessible with current experimental technology (weak measurements, controlled decoherence, cavity‑QED systems). The framework suggests that wave–particle duality can be understood as a dissipative phase transition, bridging foundational quantum theory with practical open‑system control.
Abstract The double-slit interference experiment is a core experiment in quantum mechanics. The phenomenon that observation changes the result has long been explained by the Copenhagen Interpretation as wavefunction collapse—a diffused wave contracts to a point particle upon measurement. While successful in probabilistic prediction, this interpretation faces three long-overlooked empirical difficulties in its physical picture: (1) Energy conservation: How can energy distributed over a large region instantly concentrate at a single point during collapse? (2) Total energy drop on the screen: Experimental data show that the total energy reaching the screen is significantly lower with a detector present than without, which the collapse model cannot accommodate. (3) Continuous effect of measurement strength: When detection strength is adjusted from weak to strong, interference fringes fade continuously instead of vanishing abruptly at a threshold, accompanied by a simultaneous continuous drop in total energy. All these contradict the expectation of instant collapse. This paper systematically reviews the experimental facts filtered out by mainstream narratives, then proposes an alternative model fully based on energy conservation: A photon can be regarded as an entire diffused energy cluster; the double-slit barrier splits it into two branch energies, which superimpose freely to produce interference fringes. The detector does not cause collapse but injects a probing energy field into the space behind the slits, which physically isolates the two branches and destroys the interference condition. This model relies on neither wavefunction collapse nor instantaneous action at a distance, and naturally predicts that stronger detection leads to more complete isolation, dimmer fringes, and lower total screen energy—consistent with experiments including the 2025 MIT study. This paper does not attempt to overthrow the mathematical framework of quantum mechanics, but points out that the Copenhagen Interpretation is a historically conditioned physical picture with empirical vulnerabilities. The energy cluster model proposed in this paper is superior in empirical completeness and is suitable as an alternative framework for physics education and engineering intuition. 摘要 双缝干涉实验是量子力学的核心实验之一,其“观测改变结果”的现象长期被哥本哈根诠释解释为“波函数坍缩”,即一个弥散的波在测量瞬间收缩为一个粒子。该解释虽然在概率预测上取得了成功,但在物理图像上存在三个长期被忽略的实证困难:(1)能量守恒问题:坍缩过程中,原本分布在较大空间范围内的能量如何瞬间集中于一点?(2)观测后屏幕总能量下降:实验数据表明,开启探测器后,抵达屏幕的总能量显著低于无观测状态,而坍缩模型无法容纳这一能量损失;(3)观测强度的连续效应:当探测能量从弱到强调节时,干涉条纹并非在某一阈值处突变消失,而是连续淡化,同时屏幕总能量同步连续下降。这些现象均与“突变坍缩”的预期不符。 本文首先系统回顾上述被主流叙述过滤的实验事实,随后提出一个完全基于能量守恒的替代模型:光子可视为一整块弥散的能量团,双缝挡板将其切分为两股分支能量,两支分支自由叠加从而产生干涉条纹;探测器的作用并非导致“坍缩”,而是向缝后空间注入探测能量场,这一外来能量在物理上隔离了两股分支能量,进而破坏干涉条件。该模型不依赖波函数坍缩、不涉及瞬时超距作用,并且天然预言:观测能量越强,隔离越彻底,条纹越淡、屏幕总能量越低,这一预言与MIT 2025年等实验数据高度吻合。 本文不试图推翻量子力学的数学框架,而是指出:哥本哈根诠释是在特定历史条件下形成的、存在实证漏洞的物理图像;本文提出的能量团模型在实证完整性上更具优势,适合在物理教学与工程直观中作为替代图像使用。
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.
