Against Collapses, Purity and Separability Within the Definition of Quantum Entanglement
Abstract
In this paper we we will argue against the orthodox definition of quantum entanglement which has been implicitly grounded on several widespread (metaphysical) presuppositions which have no relation whatsoever to the formalism of QM. We will show how these presuppositions have been introduced through a naive interpretation of the quantum mathematical structure which assumes dogmatically that the theory talks about "small particles" represented by pure states (in general, superpositions) which suddenly "collapse" when a measurement takes place. In the second part of this paper we will present a noncollapse approach to QM which makes no use whatsoever of particle metaphysics, escaping the need to make reference to spacetime separability or the restriction to certain predictions of definite valued binary properties. Our paper ends up concluding the essential need to redefine the notion of quantum entanglement, at least in the cases of: i) noncollapse interpretations of QM; or, ii) any other interpretation which abandons the idea that QM makes reference to "small particles".
