    "abstract": "The entanglement of general pure Gaussian two-mode states is examined in\nterms of the coefficients of the quadrature components of the wavefunction. The\nentanglement criterion and the entanglement of formation are directly evaluated\nas a function of these coefficients, without the need for deriving local\nunitary transformations. These reproduce the results of other methods for the\nspecial case of symmetric pure states which employ a relation between squeezed\nstates and Einstein-Podolsky-Rosen correlations. The modification of the\nquadrature coefficients and the corresponding entanglement due to application\nof various optical elements is also derived.",
