  In 1935, Einstein, Podolsky, and Rosen claimed the incompleteness of quantum
mechanics by assuming that local actions cannot influence the elements of
reality in a distant location. In this Letter, we show that Alice's local
quantum operations can be correlated with the quantum reality of observables in
the causally disconnected laboratory of Bob. We propose a modified optical
quantum eraser experiment that can be implemented using current technology for
verifying our theoretical predictions, without any need for retrodiction. We
simulate such an experiment using IBM quantum computers.
