    "abstract": "Using two different criteria for continuous variable systems we demonstrated\nthat pump and probe beams became quantum correlated in a situation of\nElectromagnetically Induced Transparency in a sample of Rb atoms. Our result\ncombines two important features for practical implementations in the field of\nquantum information processing. Namely, we proved the existence of entanglement\nbetween two macroscopic light beams, and this entanglement is intrinsically\nassociated to a strong coherence in an atomic medium.",
