My other problem is:
Consider now the space of 2x2 complex matrices. Show that the Pauli Matrices
|I>= 1 0
0 1
|sigma x>= 0 1
1 0
|sigma y>= 0 -i
i 0
|sigma z>= 1 0
0 -1
form an orthonormal basis for this space when k=1/2. To spare yourself from having to compute 10 different matrix products, I recommend that you write out what the inner product is for general matrices A and B first.
I'm really lost on this one! Any help getting me started would be greatly appreciated!
