REMOTE MICROMECHANICAL ENTANGLEMENT AND THE THEORY OF OBJECTIVITY

Abstract

Ralf Riedinger and collaborators’ 2018 experiment, “Remote Quantum Entanglement between Two Micromechanical Oscillators,” represents an important development in experimental quantum optomechanics because it demonstrates entanglement between engineered mechanical systems located on separate silicon chips. The devices were physically separated by approximately 20 cm and connected through an optical inter- ferometric architecture with an optical path of approximately 70 m. Mechanical modes centered around 5.1 GHz were interfaced with photons near the telecommunications wavelength of 1553.8 nm. A heralding protocol based on Stokes scattering created a delocalized single-phonon excitation, while an anti-Stokes read pulse converted the mechanical excitation back into the optical domain for measurement. The reported symmetric mechanical entanglement witness, Rm,sym = 0.74+0.08 −0.05, lies below the separability bound R = 1, leading the authors to report entanglement with confidence exceeding 99.8 percent (Riedinger et al. 2018). This article develops an expanded critical–propositional examination of that experiment in systematic dialogue with the Theory of Objectivity (TO), as developed by Vidamor Cabannas and Denivaldo Silva from 2016 through 2026. The analysis distinguishes three epistemic levels that must not be conflated: modal necessity, empirical corroboration, and analogical compatibility. In the TO, the Absolute Truths are intended to occupy a modal-ontological level: their truth, if successfully demonstrated, would not depend upon contingent experimental confirmation. Experiments nevertheless remain indispensable for testing whether operational consequences associated with those axioms are instantiated in physical phenomena. Particular attention is given to Absolute Truth One, according to which prior to the emergence of the universe there was Nothing, although this Nothing is not absolute non-being but an eternal logical and mathematical essence; Absolute Truth Two, according to which every existent element possesses a field proper and exclusive to itself that individualizes it; and Absolute Truth Five, according to which an element must be observed by, or lie within the frequency relation of, at least two other elements in order to acquire logical existence, with “observation” referring to physical relations among elements rather than human consciousness. The remaining Absolute Truths are also examined insofar as they concern infinity, boundaries, composition, and the transcendent informational element. The Riedinger experiment does not test primordial Nothingness, infinity, the cosmogonic theorem, or the cosmological eras of the TO directly. Nor does it experi- mentally establish that every element has an exclusive magnetic field, or that logical existence universally requires two observing elements. It does, however, establish a highly relevant empirical domain in which physical individuality, relational state forma- tion, loss of which-path information, optical mediation, mechanical storage, conversion between photons and phonons, and nonseparable correlations occur in a controlled system. Especially significant for the TO is the fact that the relevant physical pro- cesses require no human observer: interactions among resonators, optical modes, beam splitters, detectors, and radiation are sufficient to prepare, transform, and reveal the state. The analysis therefore concludes that Riedinger et al. provide neither a proof nor a direct confirmation of the Theory of Objectivity as a whole. They do, however, offer a strong empirical bridge to operational consequences compatible with the TO’s relational and informational ontology. The experiment is particularly fertile for the TO’s treatment of Absolute Truth Five and of the transcendent element understood as knowledge or information generated in atomic relations and associated with radiation. The article proposes a series of more discriminating future tests intended to separate broad quantum-mechanical relationality from distinctive empirical consequences that would have to follow specifically from the TO.
