From Quantum Information to Gravitation (in German)

TL;DR

This paper proposes a novel approach linking an abstract quantum information theory called Protyposis to the derivation of general relativity, offering insights into cosmology, dark energy, and spacetime structure.

Contribution

It introduces Protyposis as a foundational framework from which general relativity and cosmological phenomena can be derived based on quantum information principles.

Findings

Derivation of an isotropic, homogeneous cosmology from Protyposis.

Explanation of dark energy through the energy conditions of the theory.

General relativity emerges as a description of local inhomogeneities.

Abstract

To unite quantum theory and general relativity, in a new access it is shown that from a theory of an abstract quantum information - called Protyposis - the theory of general relativity can be deduced by means of few and physically good founded reasons. "Abstract" quantum information means that primarily no special meaning is connected with it. The resulting cosmology has an isotropic and homogeneous metric and solves the so-called cosmological problems. For the Protyposis it follows an equation of states for energy density and pressure that fulfils all the energy conditions and that also gives an explanation for the dark energy. If it is demanded that the relations between spacetime structure and the material contend also hold for deviations from this ideal cosmology than General relativity results as a description for local inhomogenities.
