This article develops an expanded critical-propositional analysis of S. Dürr, T. Nonn, and G. Rempe’s 1998 experiment, “Origin of Quantum-Mechanical Complementarity Probed by a ‘Which-Way’ Experiment in an Atom Interferometer,” published in Nature, in systematic dialogue with the Theory of Objectivity (TO) developed by Vidamor Cabannas and Denivaldo Silva. The Dürr–Nonn–Rempe experiment constitutes an especially significant empirical case because it addresses a foundational question of quantum mechanics: whether the disappearance of interference following the acquisition of which-way information must be explained through mechanical momentum disturbance, as elementary presentations of the uncertainty principle sometimes suggest, or whether complementarity emerges more fundamentally from correlations between distinguishable degrees of freedom. Using an atom interferometer based on rubidium atoms, optical Bragg diffraction, microwave manipulation of hyperfine states, and path marking through internal atomic degrees of freedom, Dürr, Nonn, and Rempe showed that interference can disappear even when the mechanical back action associated with path detection is too small to account for the observed loss of visibility (Dürr, Nonn, and Rempe 1998b). The phenomenon is instead explained through correlations between atomic motion and the internal which-way marker. Their companion quantitative experiment further examined the relation between path distinguishability D and interference visibility V , providing empirical support for the duality relation associated with Englert’s formulation, D 2 + V 2 ≤ 1. The present article examines these results under the modal and methodological discipline proposed by the Theory of Objectivity. It distinguishes three epistemological levels: (1) empirical confirmation of a physical phenomenon; (2) structural compatibility between that phenomenon and categories of the TO; and (3) specific empirical confir- mation of propositions uniquely derived from the TO. This distinction prevents the mistaken inference that an experiment compatible with an axiom thereby demonstrates the axiom’s claimed modal necessity. Particular attention is given to VA4, concerning boundary and distinction; VA5, concerning observation and relational structure; VA6, concerning composition from prior elements and relations; and VA7, concerning the transcendent element understood within the TO as knowledge or information generated in atomic relations and considered equivalent, within the theory, to atomic radiation. The experiment provides a strong empirical demonstration that physically instantiated information can be generated, stored in atomic internal states, correlated with motional alternatives, and associated with measurable changes in interference. This constitutes a potentially important indirect empirical bridge toward the informational dimensions of VA7. Nevertheless, the experiment does not by itself establish the stronger TO proposition that information is ontologically equivalent to atomic radiation, nor does it prove the necessary truth of VA1–VA7. The analysis also considers the phenomenic elements of light, electromagnetic radiation, atomic transitions, information, boundary formation, and observation; the TO concepts of Expansive and Reductive Inducing Effects (EIE/EIR); the cosmogonic theorem; and the theory’s cosmological eras. It argues that the most productive contribution of the Dürr–Nonn–Rempe experiment to the TO is not cosmological but microphysical and methodological. It suggests a possible operational program in which TO concepts of boundary, observation, and informational differentiation are mapped onto measurable quantities such as path distinguishability, coherence, visibility, mutual information, entropy, and state overlap. The resulting assessment is that the Dürr–Nonn–Rempe experiment has a high degree of dialogue with the Theory of Objectivity, particularly through VA4–VA7, while simultaneously exposing an important burden on the TO: to transform philosophical and modal correspondences into mathematically defined, quantitatively testable, and potentially discriminating empirical propositions.

This article develops an expanded critical–propositional analysis of U. Eichmann, J. C. Bergquist, J. J. Bollinger, J. M. Gilligan, W. M. Itano, D. J. Wineland, and M. G. Raizen’s 1993 experiment, “Young’s Interference Experiment with Light Scattered from Two Atoms,” published in Physical Review Letters, in systematic dialogue with the Theory of Objectivity (TO) developed by Vidamor Cabannas and Denivaldo Silva. Eichmann et al. experimentally observed interference in light scattered by two trapped atoms and showed that polarization- sensitive detection could select situations in which which-path information was physically unavailable, permitting interference, or available in principle through atomic-state correlations, suppressing it (Eichmann et al. 1993). The experiment is therefore of particular interest for TO because it connects atomic relations, radiation, distinguishability, observation, boundary conditions, and physically instantiated information within a single controlled experimental configuration. The analysis adopts a strict three-level epistemological distinction: first, empirical confirmation of physical phenomena; second, structural compatibility between those phe- nomena and TO categories; and third, specific discriminating confirmation of predictions uniquely derived from TO. This distinction is necessary because the Seven Absolute Truths of TO are presented as modally necessary premises rather than inductive generalizations. An empirical experiment cannot make a necessary proposition necessary; it can, however, test operational bridges derived from that proposition, identify physical realizations structurally compatible with it, or falsify contingent empirical consequences attributed to it (Cabannas and Silva 2026a, 2026d, 2026f). The strongest dialogue is found with VA4, concerning boundary and differentiation; VA5, concerning triangular or relational observation; VA6, concerning composition from prior elements and relations; and especially VA7, when TO’s transcendent element is interpreted as knowledge or information produced in atomic relations and identified with atomic radiation. Eichmann et al. show that atomic scattering processes create radiation and matter–radiation correlations containing physically accessible information about alternative histories of the system. Nevertheless, the experiment does not establish the ontological identity of information and radiation, nor does it independently confirm TO against standard quantum mechanics. The paper further articulates the experiment with TO phenomenic elements, the Reductive and Expansive Inductive Effects, the cosmogonic theorem, and the cosmological eras. It concludes that Eichmann et al. provide strong indirect empirical compatibility with selected operational bridges of TO, while simultaneously imposing productive constraints on any attempt to formulate information as a transcendent physical element. A quantitative research program is proposed in which visibility, distinguishability, atomic-state correlations, thermal localization, and radiation are related to explicit TO observables, thereby creating the possibility of future discriminating tests.

The 1999 experiment reported by Markus Arndt, Olaf Nairz, Julian Vos-Andreae, Claudia Keller, Gerbrand van der Zouw, and Anton Zeilinger in Nature demonstrated de Broglie matter-wave interference for C60 fullerene molecules, extending experimen- tally observable quantum coherence to an object of unprecedented mass and internal complexity at the time (Arndt et al. 1999). This article develops a complete critical– propositional analysis of that experiment in systematic dialogue with the Theory of Objectivity (TO), as developed by Vidamor Cabannas and Denivaldo Silva. The analysis distinguishes three epistemological levels that must not be conflated: the experimentally established phenomenon of molecular interference; the physical interpretation supplied by quantum mechanics and decoherence theory; and the modal- ontological claims of the TO. This distinction is essential because empirical compatibility with a modal ontology is not equivalent to demonstration of modal necessity. The C60 experiment is especially relevant to the TO in four domains. First, a complex composed object behaves as a coherent quantum unit at the level of its center- of-mass propagation, providing a meaningful point of dialogue with the compositional structure associated with Absolute Truth 6 (VA6). Second, the diffraction grating is not merely a passive geometrical boundary: molecule–surface interactions modify the effective slit width, generating an empirically measurable interface between geometry and dynamics and providing a strong operational bridge to Absolute Truth 4 (VA4). Third, the preservation or destruction of interference depends on correlations between the molecule and its environment, thereby connecting physical distinguishability, infor- mation, and radiation. This creates the most significant point of contact with Absolute Truth 7 (VA7), under which the TO identifies its transcendent element with knowledge or information produced in atomic relations and regards such information as equivalent to atomic radiation. Fourth, the experiment offers possible operational analogues for the TO’s Inducing Effects, although these analogues must not be treated as established identities without independent derivation. The article also examines possible relations to VA1–VA7, the TO phenomenic elements, the Cosmogonic Theorem, and the cosmological Eras. It argues that the C60 experiment provides selective and indirect empirical corroboration for operational projections compatible with VA4, VA6, and VA7, but does not constitute confirmation of the TO as a complete ontology. Later experiments on thermal decoherence strengthen the radiation–information bridge by showing that photon emission can reduce molecular interference when it becomes capable of encoding spatial information (Hackermüller et al. 2004). In dialogue with Heisenberg, Einstein, Bohm, Joos and Zeh, Zurek, Aspect, Planck, LIGO/Virgo, JWST observations, and Petina’s taxonomy of fundamental laws, the paper proposes a research program capable of converting qualitative TO correspondences into quantitative and potentially discriminatory predictions. The central methodological conclusion is that the scientific strength of the TO will not depend on retrospectively redescribing established quantum phenomena in its own vocabulary, but on deriving from its modal architecture measurable relations that either reproduce quantum theory from more fundamental principles or predict deviations in controlled regimes.

This article develops an expanded critical–propositional analysis of C. W. Chou and col- laborators’ 2005 experiment, Measurement-Induced Entanglement for Excitation Stored in Remote Atomic Ensembles, in systematic dialogue with the Theory of Objectivity (TO), developed by Vidamor Cabannas and Denivaldo Silva. Chou et al. (2005) experi- mentally demonstrated entanglement between two spatially separated atomic ensembles by exploiting quantum interference and indistinguishable photon detection. A single collective spin excitation was shared between ensembles separated by approximately 2.8 m and distributed over roughly 105 atoms at each site. After a programmable storage interval of approximately 1 µs, the atomic state was mapped onto propagating optical fields, allowing the experimenters to evaluate conditional photon statistics, mutual coherence, interference visibility, and lower bounds for concurrence. The measured interference visibilities reached approximately 70±2% and 71±2%, while the conditional two-photon parameters were substantially below their uncon- ditioned counterparts. Positive lower bounds for concurrence supplied quantitative evidence of entanglement. Chou et al. additionally demonstrated that, when the photon- emission alternatives were rendered distinguishable through orthogonal polarizations, the interference associated with the stored coherence was strongly suppressed (Chou et al. 2005). The analysis distinguishes three epistemological levels: (1) empirical confirmation of quantum phenomena; (2) structural compatibility between those phenomena and categories of TO; and (3) specific empirical confirmation capable of discriminating TO-derived predictions from standard quantum mechanics. The experiment clearly satisfies the first level and provides unusually rich material for the second, particularly regarding TO’s categories of boundary/interface (VA4), triangular or simultaneous observation (VA5), composition from prior elements (VA6), and the transcendent element, understood in TO as information or knowledge produced in atomic relations and associated with atomic radiation (VA7). The experiment does not, however, reach the third epistemological level, because the reported observations are quantitatively accommodated by standard quantum mechanics and quantum optics. The central proposition advanced here is that the Chou experiment nevertheless offers one of the most productive existing experimental platforms for developing operational bridges between TO and contemporary quantum physics. Its controlled sequence—optical writing, atomic collective excitation, information storage, conditional measurement, and optical retrieval—establishes a physical transformation chain connecting atomic relations, stored information, and radiation. This chain is strongly compatible with TO’s emphasis on relational constitution and information-bearing atomic processes. Yet convertibility between material and optical quantum information must not be confused with an experimentally established ontological identity between information and radiation. That distinction represents both the strongest point of dialogue and the most important point of tension. The article consequently proposes possible TO-specific extensions of Chou-type experiments, including residual-radiation tests during storage, boundary-dependent coherence tests, and quantitative comparisons between standard quantum-mechanical predictions and hypothetical TO correction terms. Such tests could move the discussion from philosophical compatibility toward discriminating empirical contact. Keywords: Theory of Objectivity; quantum entanglement; atomic ensembles; quantum memory; information; radiation; measurement; boundaries; concurrence; DLCZ; modal ontology; empirical testability.

This article develops an expanded critical–propositional analysis of Milena D’Angelo, Yoon-Ho Kim, Sergei P. Kulik, and Yanhua Shih’s 2004 experiment, “Iden- tifying Entanglement Using Quantum Ghost Interference and Imaging,” published in Physical Review Letters, in systematic dialogue with the Theory of Objectivity (TO) developed by Vidamor Cabannas and Denivaldo Silva. D’Angelo et al. investigated Einstein–Podolsky–Rosen-type entanglement in the transverse momentum and position variables of photon pairs generated through spontaneous parametric down-conversion. Their measurements yielded a momentum- sum uncertainty of ∆(kxs + kxi) = 2.5 ± 0.6 mm−1 , compared with individual transverse wave-vector uncertainties of approximately 23 mm−1 , and a position-difference uncertainty of ∆(xs − xi) = 0.11 ± 0.02 mm. They further obtained the product ∆(kxs + kxi)∆(xs − xi) = 0.3 ± 0.1 < 1. The experiment was designed to distinguish EPR-type quantum entanglement from classical momentum correlations through simultaneous satisfaction of position and momentum nonclassicality conditions (D’Angelo et al. 2004). The present analysis distinguishes three epistemological levels: empirical con- firmation of the observed quantum phenomenon; structural compatibility between the phenomenon and TO categories; and specific empirical confirmation capable of discriminating TO from standard quantum mechanics. On this basis, the experiment is found to have particularly strong structural compatibility with TO’s Fourth Absolute Truth (VA4), concerning boundary or interface; Fifth Absolute Truth (VA5), concern- ing relational observation; Sixth Absolute Truth (VA6), concerning composition; and Seventh Absolute Truth (VA7), concerning a transcendent element interpreted within TO as knowledge or information produced in atomic relations and physically associated with atomic radiation. The strongest point of contact arises from the fact that the experimentally relevant ghost-interference and ghost-image patterns do not occur in the individual counting distributions but emerge in coincidence correlations between spatially separated detection channels. The article also examines possible relations with TO’s phenomenic elements, Inductive Effects, cosmogenic theorem, and cosmological Eras. These connections are classified according to evidential strength so that experimental facts are not converted into ontological conclusions without intervening derivations. The study argues that D’Angelo et al. provides meaningful indirect empirical support for the plausibility of a relational and informational ontology but does not inde- pendently demonstrate TO, its modal axioms, its cosmogenic claims, or its distinctive interpretation of information. To transform strong compatibility into discriminatory empirical support, TO must derive quantitative predictions differing from standard quantum theory for experimentally controllable configurations involving boundaries, correlations, or information-sensitive observables. A research program for such operationalization is proposed. The final degree of dialogue between D’Angelo et al. and TO is assessed as 9.1/10: very high structural dialogue, but not exclusive empirical confirmation. Keywords: Theory of Objectivity; quantum entanglement; ghost interference; ghost imaging; EPR correlations; quantum information; relational ontology; modal necessity; phenomenic elements; Inductive Effects; VA1–VA7; spontaneous parametric down- conversion.
