Abstract

A recent proposal of a ''quantum eraser'' by Ingraham [Phys. Rev. A 50, 4502 (1994); 51, 4295(E) (1995)] is analyzed. It is shown that Ingraham's predictions contradict relativistic causality and, therefore, cannot be right. A subtle quantum effect that was overlooked by Ingraham is explained.
