    "abstract": "We present two protocols, one for the storage of light in an atomic ensemble\nand the subsequent retrieval, and another one for the generation of\nentanglement between light and atoms. They rely on two passes of a single pulse\nthrough the ensemble, Larmor precessing in an external field. Both protocols\nwork deterministically and the relevant figures of merit - such as the fidelity\nor the EPR variance - scale exponentially in the coupling strength. We solve\nthe corresponding Maxwell-Bloch equations describing the scattering process and\ndetermine the resulting input-output relations which only involve one relevant\nlight mode that, in turn, can be easily accessed experimentally.",
