    "abstract": "State preparation via conditional output measurement on a beam splitter is\nstudied, assuming the signal mode is mixed with a mode prepared in a Fock state\nand photon numbers are measured in one of the output channels. It is shown that\nthe mode in the other output channel is prepared in either a photon-subtracted\nor a photon-added Jacobi polynomial state, depending upon the difference\nbetween the number of photons in the input Fock state and the number of photons\nin the output Fock state onto which it is projected. The properties of the\nconditional output states are studied for coherent and squeezed input states,\nand the probabilities of generating the states are calculated. Relations to\nother states, such as near-photon-number states and squeezed-state-excitations,\nare given and proposals are made for generating them by combining the scheme\nwith others. Finally, effects of realistic photocounting and Fock-state\npreparation are discussed.",
