    "abstract": "We have developed a fully quantized model for EIT in which the decay rates\nare taken into account. In this model, the general form of the susceptibility\nand group velocity of the probe laser we obtained are operators. Their\nexpectation value and fluctuation can be obtained on the Fock space.\nFurthermore the uncertainty of the group velocity under very weak intensity of\nthe controlling laser and the uncertainty relation between the phase operator\nof coupling laser and the group velocity are approximately given. Considering\nthe decay rates of various levels, we may analyze the probe laser near\nresonance in detail and calculate the fluctuation in both absorption and\ndispersion. We also discuss how the fully quantized model reduces to a\nsemiclassical model when the mean photon numbers of the coupling laser is\ngetting large.",
