I was wondering according to QM do charged particles creat fields, do fields create charged particles, or are they considered one in the same (not cause-effect)?

Hi,
This is an Egg-Chicken problem!
We define each one in terms of the other. However, charged particle can not detach itself from it's field (you cann't see a charged particle without it's field). But (here comes the important bit), field can detach itself from it's source and propagate independetly, i.e. you can see field without seeing it's source, and this what light is.
For this reason (independent physical existence), we came to regard the concept of field as fundamental as that of ordinary matter.

In quantum mechanics, particles are treated as discrete units of matter or energy, while fields are continuous, pervasive quantities that permeate all of space. Particles are often described as excitations or disturbances in the underlying quantum fields.
Charged particles interact with electromagnetic fields through the exchange of virtual particles known as photons. This interaction results in the particle experiencing a force, either attraction or repulsion, depending on the charge of the particle and the strength of the field.
The key principles of quantum mechanics include superposition, uncertainty, and wave-particle duality. Superposition states that particles can exist in multiple states simultaneously, uncertainty states that there is a fundamental limit to our ability to know the exact properties of a particle, and wave-particle duality states that particles exhibit both wave-like and particle-like behavior.
In quantum mechanics, particles are represented by wave functions, which describe the probability of finding the particle in a particular location or state. Fields are represented by operators, which act on the wave function to determine the behavior of the particle in that field.
Symmetry plays a crucial role in quantum mechanics, as it helps to explain the fundamental laws and principles of the universe. In particular, symmetries such as translational and rotational symmetry, as well as gauge symmetries, are essential for understanding the behavior of particles and fields in quantum mechanics.
