I think it's obvious that something happens in an actual experiment, but it's possible that QM can't tell us what that is. In particular, it may not give us an accurate picture of what the system is really doing between state preparation and measurement.So it's possible that nothing actually happens?
Unfortunately no. These are things I had to figure out on my own, since they're not explained in any of the physics books I've read.Interesting thoughts. Do you have a web site or some article or something about this?
I haven't answered your question in the other thread yet because I need more time to think about it.
