    "abstract": "We report preparation and characterization of coherent superposition states t\n|0\u003e + alpha |1\u003e of electromagnetic field by conditional measurements on a\nbeamsplitter. The state is generated in one of the beam splitter output\nchannels if a coherent state and a single-photon Fock state |1\u003e are present in\nthe two input ports and a single photon is registered in the other beam\nsplitter output. The single photon thus plays a role of a \"catalyst\": it is\nexplicitly present in both the input and the output channels of the interaction\nyet facilitates generation of a nonclassical state of light.",
