From Quantum Information to Gravitation (in German)

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.
