Homework Statement
This isn't a homework question, but here goes:
Suppose I have a system in an initial state |[itex]\Psi_{initial}[/itex]> within the basis [itex]{|\Phi_{n}>}[/itex] and later on I have a final state |[itex]\Psi_{final}[/itex]> within the same basis, and I want to know the probability of ending up in the latter state.
Now, since [itex]<\Phi_{n}|\Psi> = c_{n}[/itex], would the probability just be [itex]|<\Psi_{final}|\Psi_{initial}>|^{2}[/itex]?
