    "abstract": "We give a description of the continuous-variable teleportation protocol in\nterms of the characteristic functions of the quantum states involved. The\nBraunstein--Kimble protocol is written for an unbalanced homodyne measurement\nand arbitrary input and resource states. We show that the output of the\nprotocol is a superposition between the input one-mode field and a classical\none induced by measurement and classical communication. We choose to describe\nthe input state distortion through teleportation by the average photon number\nof the measurement-induced field. Only in the case of symmetric resource states\nwe find a relation between the optimal added noise and the minimal EPR\ncorrelations used to define inseparability.",
