- TL;DR Summary
- If we chose Z axis when defining electron spin states, how do we choose X and Y directions then?
For a 1/2 spin particle, every pure spin state may be represented as a superposition of two states of spin parallel to some arbitrary Z axis.
(Upd) Particularly:
$$|\uparrow_{x}>=\frac{1}{\sqrt{2}}(|\uparrow_{z}>+|\downarrow_{z}>)$$
I then wonder, if we chose the Z axis, how the X axis should be chosen to make the above equality true?
