    "abstract": "The Lindblad approach to continuous quantum measurements is applied to a\nsystem composed of a two-level atom interacting with a stationary quantized\nelectromagnetic field through a dispersive coupling fulfilling quantum\nnondemolition criteria. Two schemes of measurements are examined. The first one\nconsists in measuring the atomic electric dipole, which indirectly allows one\nto infer the photon distribution inside the cavity. The second one schematizes\na measurement of photon momentum, which permits to describe the atomic level\ndistribution. Decoherence of the corresponding reduced density matrices is\nstudied in detail for both cases, and its relationship to recent experiments is\nfinally discussed.",
