We investigate coherent backscattering of light by two harmonically trapped atoms in the light of quantitative quantum duality. Including recoil and Doppler shift close to an optical resonance, we calculate the interference visibility as well as the amount of which-path information, both for zero and finite temperature.

42.25.Hz - Interference.
03.65.Yz - Decoherence; open systems; quantum statistical methods.
42.50.Vk - Mechanical effects of light on atoms, molecules, electrons, and ions.
