    "abstract": "The problem of photon adding and subtracting is studied, using conditional\noutput measurement on a beam splitter. It is shown that for various classes of\nstates the corresponding photon-added and -subtracted states can be prepared.\nAnalytical results are presented, with special emphasis on photon-added and\n-subtracted squeezed vacuum states, which are found to represent two different\ntypes of Schroedinger-cat-like states. Effects of realistic photocounting and\nFock-state preparation are discussed.",
