    "abstract": "We suggest an experimentally realizable scheme to test entanglement of a\nmixed Gaussian continuous variable state. We find that the entanglement\ncondition is simplified for the family of Gaussian states which are relevant to\nexperimental realization. The entanglement condition is then shown to be\ndirectly related to joint homodyne measurements. We show how robust the\nproposed test of entanglement is against imperfect detection efficiency.",
