ENTANGLEMENT OF REMOTE ATOMIC QUBITS AND THE THEORY OF OBJECTIVITY

This article develops an expanded critical–propositional analysis of D. N. Matsukevich, T. Chanelière, S. D. Jenkins, S.-Y. Lan, T. A. B. Kennedy, and A. Kuzmich’s 2006 experiment, “Entanglement of Remote Atomic Qubits,” published in Physical Review Letters 96, 030405, in systematic dialogue with the Theory of Objectivity (TO) formulated by Vidamor Cabannas and Denivaldo Silva. Matsukevich et al. experimentally generated entanglement between two spatially separated collective atomic qubits using a photon as the mediating quantum system. An atom–photon entangled state was initially generated at site A through Raman scattering in a cold ensemble of rubidium-85 atoms. The photonic component was transmitted through an optical fiber to site B, where electromagnetically induced transparency enabled the coherent mapping of photonic polarization information into collective atomic spin excitations. The atomic states were later converted back into photonic states and analyzed through polarization correlations. The measured Bell parameter was Sexp = 2.16 ± 0.03, exceeding the corresponding local Bell bound, |S| ≤ 2. Matsukevich et al. reported that the experimental rates were not corrected for background or detector dark counts, while their model indicated an ideal value near 2.60 (Matsukevich et al. 2006). The experiment is examined here neither as a direct proof of the complete ontology of TO nor as an empirical derivation of its Absolute Truths, but as a potential operational domain in which consequences structurally compatible with TO may be identified and distinguished from stronger propositions not established by the data. Particular attention is devoted to the Fourth, Fifth, Sixth, and Seventh Absolute Truths. The analysis argues that the experimentally realized sequence of atomic relation, photonic emission, information propagation, atomic storage, and photonic retrieval provides a particularly significant empirical analogue for the TO conception of transcendent information as information or knowledge generated through atomic relations and associated, within TO, with atomic radiation. The distinction between information carried or instantiated by radiation and the stronger TO thesis of an ontological equivalence between information and atomic radiation is maintained throughout. The Matsukevich experiment demonstrates the former proposition; the latter remains a theoretical commitment of TO requiring independent formal and empirical specification. The experiment also provides a productive domain for examination of TO’s concept of non-human observation. The protocol depends upon physical interactions, correlations, state mappings, and detector registrations, while attributing no constitutive physical role to human consciousness. This is compatible with the interpretation of the Fifth Absolute Truth according to which observation is a relation among physical elements rather than an act of human perception. Nevertheless, quantum mechanics as employed in the experiment does not establish TO’s stronger modal requirement that an element must be observed or fall within the frequency relation of at least two other elements in order to possess logical existence. The paper additionally examines possible relations between the experiment and the phenomenic elements of TO, its Expansive and Reductive Inducing Effects, its cosmogonic theorem, and its cosmological eras. The analysis concludes that Matsukevich et al. provide significant indirect empirical support for several operational bridges envisaged by TO, especially relational differentiation, composition, matter–light information transfer, and physical memory, but do not uniquely select TO over standard quantum mechanics. A stronger empirical program for TO therefore requires quantitative predictions that differ from, restrict, or supplement established quantum-mechanical predictions.
