Quantum reality via late-time photodetection

Adrian Kent

We further investigate postulates for realist versions of relativistic quantum theory and quantum field theory in Minkowski space and other background spacetimes. 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 by using photon wave mechanics and discuss possible extensions to quantum field theory.

Solution to the Lorentzian quantum reality problem

Adrian Kent

The quantum reality problem is that of finding a mathematically precise definition of a sample space of configurations of beables, events, histories, paths, or other mathematical objects, and a corresponding probability distribution, for any given closed quantum system. Given a solution, we can postulate that physical reality is described by one randomly chosen configuration drawn from the sample space. For a physically sensible solution, this postulate should imply quasiclassical physics in realistic models. In particular, it should imply the validity of Copenhagen quantum theory and classical dynamics in their respective domains. A Lorentzian solution applies to relativistic quantum theory or quantum field theory in Minkowski space and is defined in a way that respects Lorentz symmetry. We outline a solution to the nonrelativistic and Lorentzian quantum reality problems and associated generalizations of quantum theory.

Measurements in Relativistic Quantum Mechanics

Heinz‐Peter Breuer, Francesco Petruccione

Abstract This chapter develops the theory of measurements in relativistic quantum mechanics. The presentation is based on the idea to consider the state of a relativistic quantum system as a functional on the set of space-like hypersurfaces in Minkowski space. This idea leads to a manifest covariant time-evolution equation, known as Schwinger–Tomonaga equation, and allows a relativistic formulation of the projection postulate of quantum measurement theory. This postulate is used to study a number of applications to local and non-local measurements, to the erasing of local information, and to the restrictions on the measurability of non-local quantities imposed by the causality principle. The relativistic projection postulate further enables the discussion of many important problems from a unified perspective, such as EPR-type experiments, measurements of Bell state operators, exchange measurements, and quantum teleportation.
