6. Consider the state ) = (1/2) 10) + (ei/2)11). To estimate the phase , we measure [4) in the sign basis, {+),-)}. The sign basis vectors are: |+) = |0)+11) 2 1-) = 10)-11) 2 a) (5 points) Show the calculations to express the probability that the outcome of the measurement is [+). That is, derive an expression for Prob[|Y)+)]. For full credit, simplify your final expression as much as possible.
