The purpose of this paper is to propose quantum filters for a two-level atomdriven by two continuous-mode counter-propagating photons and under continuousmeasurements. Two scenarios of multiple measurements, 1) homodyne detectionplus photodetection, and 2) two homodyne detections, are discussed. Filteringequations for both cases are derived explicitly. As demonstration, the twoinput photons with rising exponential and Gaussian pulse shapes are used toexcite a two-level atom under two homodyne detection measurements. Simulationsreveal scaling relations between atom-photon coupling and photonic pulse shapefor maximum atomic excitation.
