    "abstract": "We examine various manipulations of photon number states which can be\nimplemented by teleportation technique with number sum measurement. The\npreparations of the Einstein-Podolsky-Rosen resources as well as the number sum\nmeasurement resulting in projection to certain Bell state may be done\nconditionally with linear optical elements, i.e., beam splitters, phase\nshifters and zero-one-photon detectors. Squeezed vacuum states are used as\nprimary entanglement resource, while single-photon sources are not required.",
