    "abstract": "We study the $\\Lambda$-atoms ensemble based quantum memory for the storage of\nthe quantum information carried by a probe light field. Two atomic Rabi\ntransitions of the ensemble are coupled to the quantum probe field and\nclassical control field respectively with a same detuning. Making use of the\nhidden symmetry analysis developed recently for the on-resonance EIT case (Sun,\nLi, and Liu, Phys. Rev. Lett. 91, 147903 (2003)), we show that the dark states\nand dark-state polaritons can still exist for the case of two-photon resonance\nEIT. Starting from these dark states we construct a complete class of\neigen-states of the total system. A explicit form of the adiabatic condition is\nalso given in order to achieve the memory and retrieve of quantum information.",
