Against Relativism in Quantum Entanglement

CHRISTIAN DE RONDE

Jornada; Atelier du 23 octobre 2021 à la Maison de la Connaissance et de la Création « Constante et Variable » (Orsay) : « Rencontres Quantiques »; 2021

In this talk we address the relativist-perspectival nature of the orthodox definition of quantum entanglement in terms of preferred factorizations. We also consider this aspect within the generalized definition of entanglement proposed by Barnum et al. in terms of preferred observables. More specifically, we will discuss the non-separable relativism implied by the orthodox definition of entanglement, the contextual relativism implied by its generalization as well as some other serious problems presently discussed within the specialized literature. We will address a recently proposed objective-invariant definition of entanglement understood as the actual and potential coding of effective and intensive relations. The conclusion is that, unlike with the orthodox definitions, this new objective-relational notion of entanglement is able to bypass relativism right from the start opening the door to a realist understanding of quantum correlations.
