    "abstract": "In this paper, we present a method to generate continuous-variable-type\nentangled states between photons and atoms in atomic Bose-Einstein condensate\n(BEC). The proposed method involves an atomic BEC with three internal states, a\nweak quantized probe laser and a strong classical coupling laser, which form a\nthree-level Lambda-shaped BEC system. We consider a situation where the BEC is\nin electromagnetically induced transparency (EIT) with the coupling laser being\nmuch stronger than the probe laser. In this case, the upper and intermediate\nlevels are unpopulated, so that their adiabatic elimination enables an\neffective two-mode model involving only the atomic field at the lowest internal\nlevel and the quantized probe laser field. Atom-photon quantum entanglement is\ncreated through laser-atom and inter-atomic interactions, and two-photon\ndetuning. We show how to generate atom-photon entangled coherent states and\nentangled states between photon (atom) coherent states and atom-(photon-)\nmacroscopic quantum superposition (MQS) states, and between photon-MQS and\natom-MQS states.",
