    "abstract": "We propose to use Stokes parameter as an entanglement witness for correlated\nEPR mixed states of light. Such states can be generated with a beam splitter\nacting on two mixed squeezed states of light. Stokes witness operators are\nclosely related to the Hanbury-Brown and Twiss interference and can be used to\ntest entanglement in balanced homodyne experiments involving fluctuations of\nquantum quadratures of the electric field.",
