Is wave–particle objectivity compatible with determinism and locality?

摘要: Wave–particle duality, superposition and entanglement are among the most counterintuitive features of quantum theory. Their clash with our classical expectations motivated hidden-variable (HV) theories. With emergence technologies, we can test experimentally predictions theory versus HV theories put strong restrictions on their key assumptions. Here, study an entanglement-assisted version delayed-choice experiment show that extension to controlling devices only exacerbates contradiction. We compare satisfy conditions objectivity (a property photons being either particles or waves, but not both), determinism local independence hidden variables mechanics. Any two above compatible it. The conflict becomes manifest when all three imposed persists for any non-zero value entanglement. propose conclusions. Arguably, aspects mechanics indeterminacy physical quantities ambiguity wave/particle behaviour prior measurement. Terno et al.propose models aim restore in
