    "abstract": "We examine the implications of several recently derived conditions [Hillery\nand Zubairy, Phys. Rev. Lett. 96, 050503 (2006)] for determining when a\ntwo-mode state is entangled. We first find examples of non-Gaussian states that\nsatisfy these conditions. We then apply the entanglement conditions to the\nstudy of several linear devices, the beam splitter, the parametric amplifier,\nand the linear phase-insensitive amplifier. For the first two, we find\nconditions on the input states that guarantee that the output states are\nentangled. For the linear amplifier, we determine in the limit of high and no\ngain, when an entangled input leads to an entangled output. Finally, we show\nhow application of two two-mode entanglement conditions to a three-mode state\ncan serve as a test of genuine three-mode entanglement.",
