    "abstract": "We analyze the nonlinear optical response of a five-level system under a\nnovel configuration of electro-magnetically induced transparency. We show that\na giant Kerr nonlinearity with a relatively large cross-phase modulation\ncoefficient that occurs in such system may be used to produce an efficient\nphoton-photon entanglement. We demonstrate that such photon-photon entanglement\nis practically controllable and hence facilitates promising applications in\nquantum information and computation.",
