    "abstract": "A recent discussion of quantum limitations to the fidelity with which\nsuperpositions of internal atomic energy levels can be generated by an applied,\nquantized, laser pulse is shown to be based on unrealistic physical\nassumptions. This discussion assumed the validity of Jaynes-Cummings dynamics\nfor an atom interacting with a laser field in free space, that is, when the\natom is not surrounded by a resonant cavity. If the laser field is a multimode\nquantum coherent state, and the Rabi frequency is much greater than the\nspontaneous decay rate, then the total atomic decoherence rate is on the order\nof the spontaneous decay rate. With the use of a unitary transformation of the\nfield states due to Mollow, it can be shown that the atomic decoherence rate is\nthe same as if the laser field were treated classically, without any additional\ncontribution due to the quantum nature of the laser field.",
