Quantum paradoxes in a reality model

Although there are many proposals for ontological models of reality underlying quantum mechanics, all previous approaches are either nonlocal in space-time, require additional physical effects that have not yet been observed, or include multiple additional parallel universes. This project will analyse a novel proposal for a model of quantum reality and quantum measurement, that is based on phase-space representations and retro-causal trajectories in space-time. It is a single-universe interpretation, local in space-time, which is compatible with conservation laws and existing quantum predictions of QED and QCD. The goal is to analyse multiple quantum paradoxes including: EPR paradoxes, Bell violations, Wigner’s friend, delayed choice, contextuality, and macroscopic Leggett-Garg paradoxes. The purpose here is to demonstrate that realistic "single-universe" interpretations are possible in all these cases. This will involve constructing a measurement model in each case, then demonstrating the paradox through realistic trajectories, with either analytic or numerical dynamical solutions.
