In a two state system, such as a qubit, what forces the interpretation that the system is in both states simultaneously before measurement, versus the interpretation that we just don't what state it's in before measurement? Is the latter interpretation equivalent to Einstein Realism? And if so, is this the interpretation allegedly falsified by Bell experiments? AG
It is indeed inconsistent with QM itself as Bell has shown. Experiments have later demonstrated that the Bell inequalities are violated in precisely the way predicted by QM. This then rules out local hidden variables, therefore the information about the outcome of a measurement is not already present locally in the environment.
