Contextuality from Single-State Ontological Models: An Information-Theoretic Obstruction

ArXi:2602.16716v3 Announce Type: replace Contextuality is a central feature of quantum theory, traditionally understood as the impossibility of reproducing quantum measurement statistics using noncontextual ontological models. We study classical ontological descriptions in which a fixed subsystem-level ontic state space is reused across multiple interventions.
