... the sort shown pictorially via the Feynman diagram of Fig. 1-1. It turns out that the square of the absolute value of the transition amplitude equals the probability of finding (upon measurement) that the interaction occurred. This is similar to the square of the absolute value of the wave function ...

The postulates of Quantum Mechanics
... If there are certain physical quantities, or parameters, which at least in principle can be measured, and they remain constant for a finite time interval, then we can speak about the state of the physical system. It should be noted that there is a difference between a state from the classical point ...
