Entanglement decoherence in a gravitational well according to the event formalism

TL;DR

This paper explores how a non-linear extension of quantum field theory, compatible with general relativity, predicts different entanglement behaviors in curved spacetime and assesses the feasibility of experimental tests on Earth.

Contribution

It introduces a generalized event formalism and evaluates its testability for entanglement decoherence in Earth's gravitational field.

Findings

The formalism predicts measurable deviations in entanglement distribution.

Experimental tests could distinguish this formalism from standard quantum theory.

Feasibility analysis suggests potential for practical Earth-based experiments.

Abstract

The event formalism is a non-linear extension of quantum field theory designed to be compatible with the closed time-like curves that appear in general relativity. Whilst reducing to standard quantum field theory in flat space-time the formalism leads to testably different predictions for entanglement distribution in curved space. In this paper we introduce a more general version of the formalism and use it to analyse the practicality of an experimental test of its predictions in the earth's gravitational well.
