    "abstract": "We propose a scheme allowing a conditional implementation of suitably\ntruncated general single- or multi-mode operators acting on states of traveling\noptical signal modes. The scheme solely relies on single-photon and coherent\nstates and applies beam splitters and zero- and single-photon detections. The\nsignal flow of the setup resembles that of a multi-mode quantum teleportation\nscheme thus allowing the individual signal modes to be spatially separated from\neach other. Some examples such as the realization of cross-Kerr nonlinearities,\nmulti-mode mirrors, and the preparation of multi-photon entangled states are\nconsidered.",
