I don't think you've grasped the experiment at all. The photon is
rotated in small increments up to as much as 90°, there isn't any "in
the other". Why do you not include the diagrams? You just make it
harder to discuss them.*

multiple-worlds? /
*I can do better than that, I can tell you what the inventors of the
quantum bomb tester, Elitzur and Vaidman, thought it had to do with
multiple-worlds. The following quote comes from Wikipedia: *
*/"The authors state that the ability to obtain information about the
bomb's functionality without ever "touching" it appears to be a
paradox that, they argue, is based on the assumption that there is
only a single "real" result. But according to the many-worlds
interpretation, each possible state of a particle's superposition is
real. The authors therefore argue that the particle does actually
interact with the bomb and it does explode, just not in our "world"."/*
And what does that have to do with it working? I explained why it works
without invoking any unobservable worlds. I noted that it does explode
/sometimes/, with a low probability as I showed in my diagram.
