Why (experimentally) is a set of quantons prepared in a superposition of a given observable’s eigenvectors different from a classical mixture of quantons that have “already collapsed” to the different eigenvectors (with the same probabilities as predicted by the superposition)?
A. We can (in appropriate circumstances) show that the superposition is an eigenvector of some other observable, but this is not possible for a mixture. B. We can construct situations where quantons in the superposition state exhibit interference effects that cannot be observed for a mixture. C. Both A and B. D. Neither A nor B (explain).
