TL;DR Summary
Do quasi static electric fields produced by moving entangled ions have entangled properties?
Assume I could produce a stream of calcium ions from a 2nm diameter nanotube by pushing them through the nanotube using coulomb repulsion. Assuming these coulomb repulsed ions produce a stream of entangled ions which then create a slowly emitting quasi static electric (near) field.

Even if (let’s say) after being emitted, as the ions slow down the ions interact with stuff, but at the point of ejection and production. of the quasi static electric field they were entangled.

So does anybody know if this emitted quasi static electric field (not the ions) has entangled quantum properties?

My feeling is the field has entangled properties because otherwise I could compute the quantum properties of the ions being ejected.

Entanglement is not a property (observable) of the quanta. It is a characteristic of their mode of production. Certainly, the electric field quanta produced by ions will be entangled with said ions. But I am not clear on what you actually mean by having "entangled quantum properties".

For a quantum to have some property then there must be a possible device that will indicate all systems with that property and fail to indicate all systems without that property. You can, of course, build a device which, for a composite pair of quanta, selects for a specific sharp mode which is specifically an entangled mode but you can't filter out all entangled modes from all unentangled modes. To see this note that you can construct a basis consisting of only entangled modes. If your filter passes these it will pass all modes including unentangled ones.

Finally, note that you cannot in any way measure only one half of a quantum pair and determine if it is entangled with something else. Consider this and its generalization to larger ensembles as you consider your question.
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...
I am not sure if this falls under classical physics or quantum physics or somewhere else (so feel free to put it in the right section), but is there any micro state of the universe one can think of which if evolved under the current laws of nature, inevitably results in outcomes such as a table levitating? That example is just a random one I decided to choose but I'm really asking about any event that would seem like a "miracle" to the ordinary person (i.e. any event that doesn't seem to...
