    "abstract": "We propose a scheme for continuous-variable quantum cloning of coherent\nstates with phase-conjugate input modes using linear optics. The quantum\ncloning machine yields $M$ identical optimal clones from $N$ replicas of a\ncoherent state and $N$ its replicas of phase conjugate. This scheme can be\nstraightforwardly implemented with the setup accessible at present since its\noptical implementation only employs simple linear optical elements and homodyne\ndetection. Compared with the original scheme for continuous variables quantum\ncloning with phase-conjugate input modes proposed by Cerf and Iblisdir [Phys.\nRev. Lett. 87, 247903 (2001)], which utilized a nondegenerate optical\nparametric amplifier, our scheme loses the output of phase-conjugate clones and\nis regarded as irreversible quantum cloning.",
