These are called the Bloch sphere, B-L-O-C-H. The Bloch sphere is the space of states of a qubit. And so a sphere, a two-dimensional sphere, has an infinite number of points on it, right? Because it's a smooth sphere. But even if you ignore that, you need to give me two numbers, two coordinates to tell me where you are on that sphere. And they are real-valued numbers, not integers.
