    "abstract": "We propose a method for producing on-demand single-photon states based on\ncollision-induced exchanges of photons and unbalanced linear absorption between\ntwo single-mode light fields. These two effects result in an effective\nnonlinear absorption of photons in one of the modes, which can lead to single\nphoton states. A quantum nonlinear attenuator based on such a mechanism can\nabsorb photons in a normal input light pulse and terminate the absorption at a\nsingle-photon state. Because the output light pulses containing single photons\npreserve the properties of the input pulses, we expect this method to be a\nmeans for building a highly controllable single photon source.",
