  • But that’s ignoring that there are multiple paths that can lead to state z, isn’t it?

    I’ll try to design the simplest possible experiment: you have to radioactive atoms, each connected to a detector, and the detectors are connected to a counter. You leave the room and come back - the counter shows 2. How do you determine which atom decayed first?


  • Sorry, it’s been a long time since I last looked at the mathematical side of quantum mechanics, so most of your comment flew over my head. Let me put it in as simple terms as I can:

    If there are multiple paths a system can take to reach a final state, how can you accurately determine which path was taken if you only know the initial & final state? IMO this shouldn’t be possible.



  • Hm, I’m not sure if I understand the abstract correctly.

    Say I build two Schrödingers cat experiments next to each other, and connect them so that each vial dispersing the poison also makes the other vial disperse poison. I go away, and come back to both vials having triggered and both nuclear decays having occurred. How could I determine the path the whole system took?
