... If we know the momentum p of the particle as function of x, we can calculate the expectation value ‹p›. However, it is impossible in principle to find p as function of x since, according to uncertainty principle, both p and x can not be determined at the same time. To find ‹p› we need to know the di ...

Measuring the quantum mechanical wave function
... Fortunately the proposed scheme requires us only to measure one variable Ð position Ð and this can be done with very high precision indeed [9]. So nothing can stop me from measuring the distributions Pr (n ; Ln) for a set of truly quantum particles. And no one can prevent me from entering this measu ...
