I've read that ##\left | \psi \right > =cos \frac \theta 2 \left | 0 \right > + e^{i \phi} sin \frac \theta 2 \left | 1 \right >##, and the corresponding point in the Bloch sphere is as the fig below shows.
I think ##\left | 0 \right >## and ##\left | 1 \right >## are orthonormal vectors, then why they seem to apear parallel in the Bloch sphere?
Also, I can understand the ##cos \frac \theta 2 \left | 0 \right >## part, but I cannot understand how ##e^{i \phi} sin \frac \theta 2 \left | 1 \right >## part can match the fig.
Thanks!
