*Not sure I understand. Do you mean that SINCE the system being measured is originally in a superposition, and finally becomes a mixture, it implies a denial of unitary time evolution? If so, how do you know that the final result is mixture? TIA, AG * -- You received this message because you are subscribed to the Google Groups "Everything List" group.
