    "abstract": "We analyze in details a scheme for cloning of Gaussian states based on linear\noptical components and homodyne detection recently demonstrated by U. L.\nAndersen et al. [PRL 94 240503 (2005)]. The input-output fidelity is evaluated\nfor a generic (pure or mixed) Gaussian state taking into account the effect of\nnon-unit quantum efficiency and unbalanced mode-mixing. In addition, since in\nmost quantum information protocols the covariance matrix of the set of input\nstates is not perfectly known, we evaluate the average cloning fidelity for\nclasses of Gaussian states with the degree of squeezing and the number of\nthermal photons being only partially known.",
