If in some theories I can think of electric charge as being quantized momentum around a circle could I think of Weak Charge as quantized momentum in the space T^2, a two-torus, or think of QCD's color charge as quantized momentum in the space T^3, a three torus? Certain directions in T^2 and T^3 might be forbidden? Whether wrong or right I'm just curious what is the natural continuation of thought on this matter is.

Thanks for any help!

I believe you are on the right track. What you want to say is that the various charges you mentioned may be associated with what you call 'quantized momentum' in their respective group manifold. The group manifold of U(1) is isomorphic to a circle, so that's ok. But I don't know how to visualize the group manifold of SU(2), which is a three-dimensional space, and SU(3), which is an eight-dimensional space.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference experiment is sufficient to break the interference pattern. Here are his words from the official transcript: Is that true? Caveats I see: The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might...
