I.Provide a unitary that maps |+> to |1> and |-> to |0> . Enter 0 in all boxes if no such unitary exists. (In this case, you have to enter 0 explicitly. Blanks are not accepted.)

c d
II.Provide a unitary that maps cos (30) |0> + sin (30) |1> to cos(-15) |0> + sin(-15) |1> and cos(5) |0> + sin(5) |1> to cos(-40) |0> + sin(-40) |1> . Enter 0 in all boxes if no such unitary exists.
a b
c d
Helpppp
1/sqrt(2) -1/sqrt(2)
1/sqrt(2) 1/sqrt(2)
Thanks helper, any answer for the second? Thanks
I. Is wrong?
I have got all the rest of the answers correct.. this I couldn't muster.
What is the matrix for Z⊗X (Z applied on the first qubit and X applied on the second qubit)? provide directions, hints, solution ;)
0,1,0,0
1,0,0,0
0,0,0,-1
0,0,-1,0
