<-z|x> is the amplitude for a particle in state |x> to be in state |-z>.(adsbygoogle = window.adsbygoogle || []).push({});

a particle in state |x> can be in |+x> or |-x>, correct?

|+x> = [1/sqrt(2)]|+z> + [1/sqrt(2)]|-z>

|-x> = [1/sqrt(2)]|+z> - [1/sqrt(2)]|-z>

How would this be calculated?

Would the amplitude be:

<-z|+x> + <-z|-x>?

|<-z|+x>| + |<-z|-x>|?
