    "abstract": "A common experimental setup in cavity quantum electrodynamics (QED) consists\nof a single two-level atom interacting with a single mode of the\nelectromagnetic field inside an optical cavity. The cavity is externally driven\nand the output is continuously monitored via homodyne measurements. We derive\nformulas for the optimal rates at which these measurements provide information\nabout (i) the quantum state of the system composed of atom and electromagnetic\nfield, and (ii) the coupling strength between atom and field. We find that the\ntwo information rates are anticorrelated.",
