Name: We Were WRONG About the Quantum Eraser!
Genre: Documentary, Talk
Released: 2025-10-16

Oct 16, 2025Documentary, TalkSeason 2025, Episode 21

Does quantum mechanics allow the future to retroactively influence the past, as in the infamous delayed choice quantum eraser experiment? How about we get an actual quantum physicist--who many of you already know--to show us how to do this experiment at home, and hopefully set this matter to rest.
