    "abstract": "The reduced dynamics of an atomic qubit coupled both to its own quantized\ncenter of mass motion through the spatial mode functions of the electromagnetic\nfield, as well as the vacuum modes, is calculated in the influence functional\nformalism. The formalism chosen can describe the entangled non-Markovian\nevolution of the system with a full account of the coherent back-action of the\nenvironment on the qubit. We find a slight increase in the decoherence due to\nthe quantized center of mass motion and give a condition on the mass and qubit\nresonant frequency for which the effect is important. In optically resonant\nalkali-metal atom systems, we find the effect to be negligibly small. The\nframework presented here can nevertheless be used for general considerations of\nthe coherent evolution of qubits in moving atoms in an electromagnetic field.",
