Sorry, I do not look for self-adjoint matrix, just unitary (wrong title) -- for the general form of transformation between two different bases in the 2x2 Hilbert space. I was thinking in the same direction Stirlanc, but I wonder how I can add Pauli Z matrix and still have unitary matrix with...

Hi, I am looking for the general form of 2x2 complex transformation matrix. I have the article, that says "the relative position of a self-adjoint 2x2 matrix B with respect to A as a reference (corresponding to the transformation from the eigenspaces of A to the eigenspaces of B) is determined...
