Does Time Exist at the Quantum Level with Photons in Two Places?

As in quantum mechanics a photon can find itself at 2 different places at the same time, does time then exists at that level ?

In relativity, the phrase "two different places at the same time" is strictly meaningless. This is called the relativity of simultenaity.
 
At what level?
 
I don't know what you mean by "level". Can you clarify?
 
Sorry, selfAdjoint; I was initiating picass.
 
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...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
