These experiments have been done and are essentially equivalent to Deutsch's thought experiment. There is no mystery in interpreting these experiments. In all cases, if the which-way information is preserved, no interference is seen. But if the which-way information is quantum erased, interference is visible. How this works in the delayed choice set-up has been explained by Sabine Hossenfelder. http://backreaction.blogspot.com/2021/10/the-delayed-choice-quantum-eraser.html Bruce -- You received this message because you are subscribed to the Google Groups "Everything List" group.
