| Abstract |
|
| |
It is often stated that a measurement is to establish the
probability correlation between the measured object and the measuring
apparatus. However, the precise meaning of this statement does not
seem to be understood consistently.
Here, we shall discuss this problem, and clarify how the establishment of
a measurement is related to the contextuality of quantum mechanics. From
this point of view, we discuss the simultaneous measurability of
non-commuting observables, Bohr's reply to EPR's paradox and
failure of the propensity interpretation.
