*If you make the original Elitzur-Vaidman Bomb Detector more complicated
you can increase its efficiency, but making a thought experiment more
complicated than necessary does not make it a better thought experiment. *

polarized up and in the other it is polarized down. *

*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"."*

his talk by bluntly saying Many Words is by far the best quantum
interpretation: *
