    "abstract": "We propose a simple scheme to generate an arbitrary photon-added coherent\nstate of a travelling optical field by using only a set of degenerate\nparametric amplifiers and single-photon detectors. Particularly, when the\nsingle-photon-added coherent state (SPACS) is observed by following, e.g., the\nnovel technique of Zavatta \\emph{$et al.$} (Science 306, 660 (2004)), we also\nobtain the generalized optical entangled $W$ state. Finally, a qualitative\nanalysis of possible losses in our scheme is given.",
