Standard double-slit and interferometer experiments treat apparatus geometry, boundary conditions, coherence, detector response, and which-path distinguishability as sufficient variables for predicting interference visibility. This paper preserves that standard quantum-optical null model as the baseline and asks a narrower residual question: whether a dynamically reconfigured two-path apparatus can show visibility dependence on the time at which the relevant apparatus context becomes locally available. The proposed apparatus-context hypothesis is intentionally carrier-neutral. It may be represented inside the broader space-cell program either by deformation-like geometry, stress, shear, or topology variables, or by an extrinsic scalar χ-like compression/event-density coordinate. The first experimental question is not which internal carrier is correct. It is whether any additional finite-speed apparatus-context variable is required after ordinary quantum-optical effects are modeled and controlled. The primary observable is residual visibility as a function of reconstructed apparatus-context delay, Δ_ctx = τ_interaction − τ_context available. Under this sign convention, Δ_ctx < 0 means the photon-apparatus interaction occurs before the relevant two-path context has become available, while Δ_ctx > 0 means the context is available before interaction. The proposed support signature is a reproducible negative residual in the negative-Δ_ctx timing window, absent in sham-switch, one-path, decoherence, detector-angle, path-phase, material, and deformation-only controls. The proposed experiment reflects findings from toy-model interaction/accounting tests and design-translation results. These simulations sharpen criteria for a falsifiable experiment, define controls, and translate the timing variable into implementable design constraints.

This note proposes a simple, falsifiable interferometric test for structured deviations from standard two-path interference. In conventional interference, the observed intensity is described by a single effective phase parameter: I(ϕ)=P1+P2+2P1P2cosϕ, and deviations are typically attributed to visibility loss or phase offset. The present protocol tests for a different class of behaviour: phase-locked deviations that depend on the internal structure of the phase profile applied to one arm of the interferometer. A controlled phase modulation of the form ϕ(x)=n⋅f(x)\phi(x) = n \cdot f(x) ϕ(x)=n⋅f(x) is introduced in one arm, where nn n indexes the complexity of the imposed phase structure. The resulting interference signal is measured as a function of the global phase and decomposed into quadrature components: In(ϕ)=Cn+Vn[Ancosϕ+Bnsinϕ]. A deviation metric is defined relative to the baseline (flat-phase) case: Δn=(An−A0)2+(Bn−B0)2. The testable prediction is that, if structured phase-dependent effects are present, then: the baseline satisfies Δ0≈0\Delta_0 \approx 0 Δ0≈0; the deviation Δn\Delta_n Δn increases systematically with the imposed phase structure, and the deviation remains phase-locked in the quadrature basis and cannot be absorbed into a simple phase offset. The protocol includes explicit control conditions to distinguish such behaviour from conventional effects: symmetric modulation of both arms should eliminate the deviation; random phase noise should reduce visibility but not produce systematic scaling in Δn\Delta_n Δn; and phase referencing is required to resolve the quadrature structure. The outcome is binary. If no structured deviation is observed, the hypothesis is falsified. If a phase-locked, structure-dependent deviation is observed, then the standard interference model is incomplete under these conditions. This proposal is intentionally model-independent. While motivated by broader work on structured phase transport in discrete systems, the experimental test does not rely on that framework and can be evaluated directly.
This work presents a unified, interpretive account of quantum interference and delayed-choice experiments that applies equally to photons and massive particles. Rather than invoking spacetime trajectories, wave–particle duality, retrocausality, or collapse postulates, the paper locates quantum interference in the coherent evolution of internal, pre-geometric degrees of freedom defined over classical spacetime. Within this framework, “which-path” questions are not merely unanswered but fundamentally ill-posed: interference arises from global coherence of an internal field subject to experimental boundary conditions, while spacetime itself remains single-valued and classical at laboratory scales. The approach reproduces all standard quantum-mechanical predictions without modification and is explicitly interpretive rather than predictive. A central result is a unified explanation of why interference occurs across disparate physical systems—photons, electrons, atoms, and molecules—while decoherence manifests through system-dependent physical mechanisms. Photons and massive particles differ in how internal coherence is lost (e.g., electromagnetic absorption versus collisional and thermal interactions), but not in the underlying principle. Delayed-choice experiments are reinterpreted without paradox: changes to the apparatus modify boundary conditions for the internal field rather than retroactively altering particle histories. By removing spacetime paths from the fundamental ontology, the framework offers a consistent, path-free account of interference, decoherence, and localized detection that preserves the empirical success of quantum mechanics while clarifying its conceptual foundations.
Interference phenomena are commonly understood as consequences of path indistinguishability and coherence constrained by the availability of which-path information. While delayed-choice and quantum eraser experiments have demonstrated that interference can be restored or suppressed depending on measurement context, such effects are typically implemented through discrete, externally imposed experimental configurations. In this work, propose a delayed-choice interferometric scheme in which interference visibility is regulated adaptively via predictive estimates of informational accessibility. The proposed architecture introduces an operational measure of predictability derived from ensemble-level intensity statistics, which is used to control downstream interferometric elements after the system has traversed the interferometer. This design preserves the delayed-choice character of the experiment while avoiding any modification of standard quantum mechanical formalism or assumptions of retrocausality. Predictability is treated as an informational control parameter rather than as an intrinsic property of the system’s past evolution. The scheme builds upon established complementarity relations and information-theoretic approaches to coherence and decoherence, extending them toward adaptive, feedback-based control of interference. The proposal is experimentally accessible using classical or semi-classical optical components and does not rely on single-particle detection. By reframing interference as a dynamically regulated informational regime, the work provides a bridge between foundational concepts of quantum measurement and practical architectures for coherence control.
Canonical slit-based photon experiments are commonly described through wave–particle terminology and measurement-based narratives. Here we present a physically conservative reformulation grounded in geometry-conditioned propagation, detector-induced modification of slit-conditioned fields, operational phase-accessibility, and comparative throughput control, without modifying standard quantum-optical formalism. Within a unified field-based representation, the detected intensity is decomposed into a geometry-conditioned contribution and a phase-sensitive cross contribution, while detector interaction is treated as acting at two distinct structural levels: through a detector-induced transfer factor Λ, which modifies the slit-conditioned field itself prior to screen formation, and through a phase-accessibility factor V, which governs the observable weighting of the phase-sensitive cross term. A further distinction is introduced through the comparative flux variable Φ, which controls whether differences between configurations should be interpreted structurally or merely as consequences of unequal throughput. In this framework, geometric incidence α produces deterministic phase re-referencing, finite structural thickness t produces intra-path phase redistribution, and residual comparison through ΔI(θ) provides a quantitative test of whether detector-associated double-slit patterns are strictly reducible to true single-slit limits under matched geometric and flux conditions. The formulation also predicts experimentally resolvable visibility changes arising from spatial averaging under controlled angular-distribution conditions, even when phase-accessibility remains maximal. Fully consistent with decoherence theory and standard quantum optics, this framework provides an operationally testable basis for separating geometric, structural, coherence-level, and throughput effects in canonical photon interference experiments.

Experimental Design for Measuring the Time Delay of Interference Fringe Switching Induced by Observation System Complexity This paper proposes an experimental scheme to measure the relationship between the complexity of the observation system and the time delay in double-slit interference. Traditional quantum mechanics (Copenhagen interpretation) holds that wave function collapse induced by observation is an instantaneous process. Parallel Intersection Studies (PIS) predicts instead that observation is a temporal process: the change of interference fringes involves a measurable time delay Δt. The experiment uses femtosecond laser synchronization, polarizer/coil switching, and streak camera capture to measure the time delay Δt of fringe switching after the observation apparatus intervenes. The experiment is divided into three levels, with precision improving from nanosecond to femtosecond scales. In addition, this paper proposes a "cyclic averaging mode" as a low-cost replication pathway: through repeated cyclic measurements, statistical averaging is used to trade for time resolution, enabling ordinary university physics laboratories to make preliminary judgments on Δt. Core criteria: First layer — whether Δt exists. If Δt is confirmed to be 0 (measurement precision better than theoretical expected magnitude), PIS is falsified; if Δt exists, the existence of parallel spaces is confirmed. Second layer — whether Δt varies with observation system complexity. To our knowledge, no systematic study has yet taken the observation apparatus's own complexity as an independent variable to measure its correlation with time delay. The theoretical basis of this experimental scheme (PIS axiom system and energy formula) is described in the companion preprint "Parallel Intersection Studies: A Unified Theoretical Framework Based on Scale Relativity and Parallel Relativity". V1.2: Added distinction from existing work (decoherence, objective collapse models, quantum eraser), added error budget table, added quantitative definition of observation system complexity, added cyclic averaging mode, revised the "first experiment" claim to a more conservative formulation, unified time scale notation, added blind test operational detail, added upgrade logic for three-level scheme, added cost estimation ranges, and added reference list.
