Entanglement as a Non-Discriminant Witness: A Structural Diagnostic on Operational Algebras in Weak-Field Gravity
Year: 2026
Type: article
Abstract: This technical note addresses a narrow structural question in the current gravity debate: whether the mere presence of entanglement, within a fixed experimentally accessible domain, can function by itself as a discriminator between incompatible theoretical architectures. Working within a fixed operational algebra of accessible observables, the note shows that entanglement, considered solely as a binary witness, is not by itself sufficient for such discrimination. The result is strictly diagnostic and domain-bounded: it does not deny the relevance of entanglement in quantum gravity, nor does it claim observational equivalence in principle between classical and quantum gravity. It argues instead that discrimination requires analysis of the full observable algebra and of the scaling structure of accessible correlations, not merely the presence or absence of entanglement
