    "abstract": "We study the influence of a lossless material medium on the coherent storage\nand quantum state transfer of a quantized probe light in an ensemble of\n$\\Lambda $-type atoms. The medium is modeled as uniformly distributed two-level\natoms with same energy level spacing, coupling to a probe light. This coupled\nsystem can be simplified to a collection of two-mode polaritons which couple to\none transition of the $\\Lambda$-type atoms. We show that, when the other\ntransition of $\\Lambda$-type atoms is controlled by a classical light, the\nelectromagnetically induced transparency can also occur for the polaritons. In\nthis case the coherent storage and quantum transfer for photon states are\nachievable through the novel dark states with respect to the polaritons. By\ncalculating the corresponding dispersion relation, we find the ensemble of the\nthree-level atoms with $\\Lambda$-type transitions may serve as quantum memory\nfor it slows or even stops the light propagation through the mechanism of\nelectromagnetically induced transparency. the corresponding dispersion\nrelation, we find the ensemble of the three-level atoms with $\\Lambda$-type\ntransitions may serve as quantum memory for it slows or even stops the light\npropagation through the mechanism of electromagnetically induced transparency.",
