Graviton Emission and Loss of Coherence

Abstract

The decoherence effect due to emission of gravitons is examined. It shows the same qualitative features of the QED effect which has already been investigated, it is obviously much weaker, wholly universal and shows a stronger energy dependence. The result can be extended to photons, they also may undergo decoherence due to graviton emission. For this limited aim the incomplete status of the quantum gravity, in comparison with QED, is not source of severe difficulties because all the effects are attributed to the infrared sector of the dynamics.
