Are these three statements true:
(1) We can observe where A hits (thereby seeing A as a particle instead of a wave) before B’s path determines the availability of information?
(2) Measuring where A hits, (even if done with thousands of previous data points of A sorted by B hits showing the interference patterns) has no predictive power over whether B’s whichpath information will be erased or not?
(3) Whether or not B’s whichpath information was erased, has predictive power over where A landed?
Sorry it took me so long to see this! But thank you for the reply. I will sit on it and read it slowly and try to slowly understand. :)
