Unformatted text preview: time t and then measure the position of the quantum particle for example by a photographic plate. After a large number of particles have been measure, the image corresponds to the probability distribution at time t. The time averaged probability distribution: If the position is measured at random times after the preparation of the equivalent states, the interferences between different eigenstates of the Schr dinger equation wash out . dx t x 2 | ) , ( | =- = ) ( ) , ( n t i n n n E e x A t x = =- = * * 2 | ) , ( | m n t i m n m n m E n E e A A t x = = 2 2 2 | ) ( | | | | ) , ( | n n n t x A t x...
