    "abstract": "We present a scheme for realization of quantum mechanical weak values of\nobservables using entangled photons produced in parametric down conversion. We\nconsider the case when the signal and idler modes are respectively in a\ncoherent state and vacuum. We use a low efficiency detector to detect the\nphotons in the idler mode.This weak detection leads to a large displacement and\nfluctuations in the signal field\u0027s quantum state which can be studied by\nmonitoring the photon number and quadrature distributions.",
