Imagine firing one electron at a time at a double slit. Clearly the wave function interacts with the atoms of the material, and presumably many electrons do not pass through. Why does decoherence from these interactions not spoil the experiment?
The question has been asked before, but there is no answer
Edit, to clarify the question: since the electron wave function interacts with the atoms of the material in which the double slit is cut, I naively expect that decoherence would make the system classical, no matter how carefully the experiment is set up. I must be misunderstanding the decoherence mechanism that prevents macroscopic systems being in quantum superpositions. The question is, why doesn't this decoherence spoil the double slit experiment? Can anyone explain why decoherence ensures Schrodinger's cat is alive or dead, but does not ensure the electron goes through one slit or the other?
