corresponds to 180°. This means we turn the sphere completely upside down. 0 moves to 1 and 1 moves to 0, which is why this operation acts as a NOT. To do half a NOT we could simply use half this angle: u3(0.5*pi,0,0). So now we have yet another way to perform a NOT on our qubit: We could do half a
