Content: the measurement problem. As a preview, there are some interpretations of quantum mechanics where the distinction is entirely meaningless. There is no 'quantum observer effect' (or wavefunction collapse, as it is known technically). The Stanford Encyclopedia of Philosophy also has a number of good articles on the measurement problem and interpretations of quantum mechanics. I don't understand you last few questions. Maybe if you rephrase a bit I could give an answer. Share

I am going to try to ask this question from the point of view of the Copenhagen interpretation of quantum mechanics (pioneered by Niels Bohr). However, regardless of the overall interpretation, the mathematical description of measurements in quantum mechanics is a well-established theory. The interpretation of the quantum state in the Copenhagen view, is that it represents the amount of information available about a physical system . What is peculiar about quantum mechanics is, that this information is limited in a specific sense.
