Hi!

As a layman in quantum physics area i, without any sort of prejudice or judgement of any kind, would like to know how does quantum physics explain the phenomena of oracles.

OK, I'll bite. What's 'the phenomena of oracles'?

Hey. maybe i should have written more clearly. what i wonder is that oracles such as nostradamus or edgar cayce are phenomena themselves. how do quantum physics explain such phenomena? what is an oracle according to quantum physics.
 
I would guess that if such an oracle ever existed, it would be fully explained by the density matrix as anything else. I do, however, believe that most physicists don't believe in such phenomena as oracles as the ones you describe.

Quantum mechanics has nothing to say about the supposed abilities of such "oracles". And discussion of such pseudoscience is not permitted on PF. (See our rules, which are linked at the top of every page.)
 
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...
