This essay considers the question of the ontology of relativistic quantum field theory (RQFT). It aims to discuss possible implications of the peculiarities of quantum entanglement and quantum non-loc...

Causation Counterfactuals Relativity Entanglement
2016/6/13
We investigate whether standard counterfactual analyses of causation (CACs) imply that the outcomes of space-like separated measurements on entangled particles are causally related. While it has somet...
Delayed-Choice Experiments and the Metaphysics of Entanglement
Delayed-choice experiments double-slit experiment entanglement swapping quantum eraser realism

Delayed-choice experiments in quantum mechanics are often taken to undermine a realistic interpretation of the quantum state. More specifically, Healey has recently argued that the phenomenon of delay...

Of the many and varied applications of quantum information theory, perhaps the most fascinating is the sub-field of quantum computation. In this sub-field, computational algorithms are designed which ...
Entanglement, Upper Probabilities and Decoherence in Quantum Mechanics

Computation of decay time for entangled quantum systems is an important aspect of decoherence theories. Here we explore this topic from the standpoint of computing the decay time to the existence of a...
This paper analyses the phenomenon of entanglement exchange in Bohm's pilot wave interpretation of quantum mechanics. The interesting feature of the phenomenon is that systems become entangled without...
Disproofs of Bell, GHZ, and Hardy Type Theorems and the Illusion of Entanglement
Bell's Theorem Local Realism EPR Argument Non-locality
2009/6/4
An elementary topological error in Bell's representation of the EPR elements of reality is identified.Once recognized, it leads to a topologically correct local-realistic framework that provides exact...
