- Abstract: The entropic dynamics (ED) approach to quantum mechanics is ideally suited to
address the problem of measurement because it is based on entropic and Bayesian
methods of inference that have been designed to process information and data.
The approach succeeds because ED achieves a clear-cut separation between ontic
and epistemic elements: positions are ontic while probabilities and wave
functions are epistemic. Thus, ED is a viable realist psi-epistemic model. Such
models are widely assumed to be ruled out by various no-go theorems. We show
that ED evades those theorems by adopting a purely epistemic dynamics and
denying the existence of an ontic dynamics at the subquantum level.

Unavoidable coupling of quantum systems to external degrees of freedom leads to dissipative (non-unitary) dynamics.
We introduce a method to deal with these systems based on the calculation of (dissipative) lattice Green's function.
We illustrate the power of this method with several examples of driven-dissipative bosonic chains of increasing complexity.

Non-Markovian effects are important in modeling the behavior of open quantum systems in solid-state physics, quantum optics, and in study of biological and chemical systems.
We show that under some physically motivated assumptions on the system-environment interaction, the finite-time dynamics of the non-Markovian open quantum system computed with a sufficiently large number of modes guaranteed to converge is an approximation.
Our results lend rigor to classical and quantum algorithms for approximating non-Markovian dynamics.

Rather than modelling the dynamics of the fields, ED models the dynamics of their probabilities.
A particularly significant prediction of this ED model is that the coupling of quantum fields to gravity implies violations of the quantum superposition principle.
