Abstract
The impossibility of using quantum nonlocality for controllable signalling is widely accepted in the literature. However, a critical examination of the proof strategies used to establish this claim shows that they are circular, in the sense that they depend upon locality assumptions that grant what needed to be proven in order to establish no-signalling, or which were embedded ad hoc in the formalism of quantum theory precisely in order to block predictions of signalling. We conclude that forty-five years after the publication of Bell's Theorem, the question of signalling remains open.
