From a Many Worlds point of view at least, they absolutely could, because the superposition represents ignorance in the mind of infinitely many Wigners, but once you remove the ambiguity you are just dealing with one specific Wigner, who would then know which Everett branch he is actually on (at least ip to the ambiguity of this particular experiment).
- gus_massa 8y agoIn this experiment, in both branches he receives the same information "A measure has been done.", so it doesn't remove the ambiguity, and it doesn't destroy the superposition.
