Any individual experimenter will only see one basis state as a result of his measurement, but according to Hugh Everett's idea about Many Worlds some observer somewhere will see every possible basis state; and I think Everett was probably correct. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* What I mean is that one of the basis states will be the result of a measurement, not all. But the question I am asking is the state of the system before measurement. Is the system in all basis states before measurement, like the person traveling from Dallas to NY city can be described as being in all basis sets simultaneously, even those not orthogonal?
