Determine the column vectors representing the states |+x> and |-x> using the states |+y> and |-y> as a basis.
The Attempt at a Solution
The hint my prof gave us was that since |+x> = 1/√2|+z> + 1/√2|-z> we can eliminate the states |+z> and |-z> in favor of |+y> and |-y>
I'm just lost I guess, i'm not sure how to eliminate the z states in favor of y. Any further hint or suggestion would be much appreciated.
