    "abstract": "The separability of the continuous-variable EPR state can be tested with\nHanbury-Brown and Twiss type interference. The second-order visibility of such\ninterference can provide an experimental test of entanglement. It is shown that\ntime-resolved interference leads to the Hong, Ou and Mandel deep, that provides\na signature of quantum non-separability for pure and mixed EPR states. A\nHanbury-Brown and Twiss type witness operator can be constructed to test the\nquantum nature of the EPR entanglement.",
