    "abstract": "The behavior of an atomic double lambda system in the presence of a strong\noff-resonant classical field and a few-photon resonant quantum field is\nexamined. It is shown that the system possesses properties that allow a\nsingle-photon state to be distilled from a multi-photon input wave packet. In\naddition, the system is also capable of functioning as an efficient\nphotodetector discriminating between one- and two-photon wave packets with\narbitrarily high efficiency.",
