    "abstract": "We investigate the security against collective attacks of a continuous\nvariable quantum key distribution scheme in the asymptotic key limit for a\nrealistic setting. The quantum channel connecting the two honest parties is\nassumed to be lossy and imposes Gaussian noise on the observed quadrature\ndistributions. Secret key rates are given for direct and reverse reconciliation\nschemes including postselection in the collective attack scenario. The effect\nof a non-ideal error correction and two-way communication in the classical\npost-processing step is also taken into account.",
