Homework Statement
Find the expansion coefficients of a generic vector (λ, μ) ∈ ℂ^2 in the orthonormal basis:
{ i/sqrt(2) (1, 1), 1/sqrt(2) (1, -1) }
Homework Equations
λ_i = |v_i> |v>
The Attempt at a Solution
I don't think this should be difficult.
But, clearly, as I am posting here, I do not understand the terminology used yet.
So the question says "generic" vector, so I am assuming we choose some values say
λ = (x, y)
and then we simply say
λ_x = |x> |isqrt(2) (1,1)>
Which would be x*i/sqrt(2)
What am I doing wrong here? It can't be that straightforward?
