What about if one path length is longer than the other, by either more than one light-beam length, or, in the case of an individual photon, more than one light-photon length? I’m assuming that matching two different paths to that level of precision is improbable even intentionally.
Can a beam of light or a single photon interact with itself non-locally? What if the alternate path has a different detector intermittently intercepting it?
Yep, Maxwell equations do produce the same results. The fun quantum thing is that this also happens with individual photons.
