Query: Graviton Emission and Loss of Coherence   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.
