Abstract

The Delayed-Choice Quantum Eraser experiment is commonly interpreted asimplying that in quantum mechanics a choice made at one time caninfluence an earlier event. We here suggest an extension of theexperiment that results in a paradox when interpreted using a localrealist interpretation combined with backward causation("retrocausality"). We argue that resolving the paradox requires givingup the idea that, in quantum mechanics, a choice can influence the past,and that it instead requires a violation of Statistical Independencewithout retrocausality. We speculate what the outcome of the experimentwould be.
