Abstract

In this paper, quantum filtering for a two-level atom, which is illuminated by two counter-propagating single-photon pulses, has been considered. The scenario is equivalent to that the two-level atom is driven by two input light field channels, each of which contains a single-photon. Based on two homodyne detection measurements, filtering equations in the Schrödinger picture have been derived explicitly.
