    "abstract": "We suggest a general scheme for quantum state engineering based on\nconditional measurements carried out on entangled twin-beam of radiation.\nRealistic detection schemes such as {\\sc on/off} photodetection, homodyne\ndetection and joint measurement of two-mode quadratures are analyzed in\ndetails. Imperfections of the apparatuses, such as nonunit quantum efficiency\nand finite resolution, are taken into account. We show that conditional {\\sc\non/off} photodetection provides a reliable scheme to verify nonclassicality,\nwhereas conditional homodyning represents a tunable and robust source of\nsqueezed light. We also describe optical teleportation as a conditional\nmeasurement, and evaluate the degrading effects of finite amount of\nentanglement, decoherence due to losses, and nonunit quantum efficiency.",
