Dear Shan,
I would make one comment regarding the following statement in Abstract of the article “Quantum theory cannot consistently describe the use of itself” by Daniela Frauchiger and Renato Renner, arXiv:1604.07422v2:

“Analyzing the experiment under this presumption, we find that one agent, upon observing a particular measurement outcome, must conclude that another agent has predicted the opposite outcome with certainty. The agents’ conclusions, although all derived within quantum theory, are thus inconsistent.”

However, in my opinion, the conclusions of these agents were derived contrary to quantum theory, since this theory does not allow any conclusions to be drawn on the basis of a single measurement result. Strictly speaking, one can speak about the properties of a quantum system only after measurements have been carried out in an infinite set of identical experiments – all the predictions of quantum theory concern quantum ensembles!

I hope that this comment is true and relevant here.
