Quantum Reality via Late Time Photodetection

TL;DR

This paper explores realist interpretations of relativistic quantum theory by introducing local variables dependent on late-time electromagnetic measurements, with implications demonstrated through photon wave mechanics examples.

Contribution

It proposes a novel approach to realist quantum theories in Minkowski space using late-time photodetection, extending ideas to quantum field theory.

Findings

Local variables depend on late-time electromagnetic outcomes.

Illustrations provided through photon wave mechanics examples.

Discussion on extending the approach to quantum field theory.

Abstract

We further investigate postulates for realist versions of relativistic quantum theory and quantum field theory in Minkowski space and other background space-times. According to these postulates, quantum theory is supplemented by local variables that depend on possible outcomes of hypothetical measurements on the late time electromagnetic field in spacelike separated regions. We illustrate the implications in simple examples using photon wave mechanics, and discuss possible extensions to quantum field theory.
