Decoherence and noise in an environment of photons and gravitons

I shall first discuss the electromagnetic environment as it appears in classical and quantum mechanics. Its role in the modification of the Hamiltonian formulation of classical and quantum mechanics is well-known. Only perturbative electrodynamics is relevant in such a problem. I argue that in a similar way perturbative (classical or quantum) gravity has some observable consequences in a measurement of CMB temperature fluctuations and detection of gravitational waves.
