    "abstract": "A single three-level atom driven by a longitudinal mode of a high-Q cavity is\nused to implement two-qubit quantum phase gates for the intracavity field. The\ntwo qubits are associated to the zero-and one-photon Fock states of each of the\ntwo opposite circular polarization states of the field. The three-level atom\nyields the conditional phase gate provided the two polarization states and the\natom interact in a $V$-type configuration and the two photon resonance\ncondition is fulfilled. Microwave and optical implementations are discussed\nwith gate fidelities being evaluated against several decoherence mechanisms\nsuch as atomic velocity fluctuations or the presence of a weak magnetic field.\nThe use of coherent states for both polarization states is investigated to\nassess the entanglement capability of the proposed quantum gates.",
