    "abstract": "We propose and experimentally realize a new scheme for universal\nphase-insensitive optical amplification. The presented scheme relies only on\nlinear optics and homodyne detection, thus circumventing the need for nonlinear\ninteraction between a pump field and the signal field. The amplifier\ndemonstrates near optimal quantum noise limited performance for a wide range of\namplification factors.",
