I haven't taken any course in quantum field theory or read any advanced books about it, but I would like to make what I think is a deduction.

An electric field can be explained by changing magnetic field. Provided that some property of this changing magnetic field was met, the electric field may correspond to the electric field produced by a subatomic particle. So far, I don't know of any other type of field that would generate an electric field other than a changing magnetic field. Do the quantum physicists explain the electric field of subatomic particles this way? Do they know the changing magnetic field that would be necesary to generate the electric potential of the proton for instance?

You don't need a changing magnetic field to make an electric field, electric fields are inherent properties of charged particles. If you're saying the only 'field' that can generate an electric field is a changing magnetic one you are correct, however using this sort of field thinking is, as far as i know, being phased out in this line of thought and replaced with particle physics, whereby the force carriers of the EM fields are photons.

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!
