Does Quantum Information Require Additional Structure?

Abstract

We consider the status of quantum information in the quantum theory and based on the correspondence principle, we propose an interpretation of the wave function as a mathematical representation of quantum information. We consider Clauser's analysis of incompatibility formulations of quantum theory in laboratory space and configuration-space in the context of local realism. Then, we introduce the hypothesis of quantum space of directly unobserved relations, which precede quantum correlations, and are compatible with the Reichenbach common cause principle. The possible implications of the hypothesis are discussed in the context of the latest experimental and theoretical results on the dynamics of entanglement formation in helium atoms. Finally, we present the Chyli\'nski model as an example of quantum relational continuum space, which predicts potentially measurable effects for the bound states.
