    "abstract": "We analyze the nonlinear optical response of a six-level atomic system under\na configuration of electromagnetically induced transparency. The giant\nfifth-order nonlinearity generated in such a system with a relatively large\ncross-phase modulation effect can produce efficient three-way entanglement and\nmay be used for realizing a three-qubit quantum phase gate. We demonstrate that\nsuch phase gate can be transferred to a Toffoli gate, facilitating practical\napplications in quantum information and computation.",
