Quantum reality via late-time photodetection

23 Feb 2018

We further investigate postulates for realist versions of r elativistic quantum theory and quantum field theory in Minkowski space and other background space-t imes. According to these postulates, quantum theory is supplemented by local variables that depe nd on possible outcomes of hypothetical measurements on the late time electromagnetic field in space like separated regions. We illustrate the implications in simple examples using photon wave mecha nics, and discuss possible extensions to quantum field theory.
