    "abstract": "We propose two probabilistic entanglement concentration schemes for a single\ncopy of two-mode squeezed vacuum state. The first scheme is based on the\noff-resonant interaction of a Rydberg atom with the cavity field while the\nsecond setup involves the cross Kerr interaction, auxiliary mode prepared in a\nstrong coherent state and a homodyne detection. We show that the\ncontinuous-variable entanglement concentration allows us to improve the\nfidelity of teleportation of coherent states.",
