    "abstract": "We provide a class of inequalities whose violation shows the presence of\nentanglement in two-mode systems. We initially consider observables that are\nquadratic in the mode creation and annihilation operators and find conditions\nunder which a two-mode state is entangled. Further examination allows us to\nformulate additional conditions for detecting entanglement. We conclude by\nshowing how the methods used here can be extended to find entanglement in\nsystems of more than two modes.",
