    "abstract": "We report an experiment on mapping a quantum state of light onto the ground\nstate spin of an ensemble of Cs atoms with the life time of 2 milliseconds.\nQuantum memory for one of the two quadrature phase operators of light is\ndemonstrated with vacuum and squeezed states of light. The sensitivity of the\nmapping procedure at the level of approximately one photon/sec per Hz is shown.\nThe results pave the road towards complete (storing both quadrature phase\nobservables) quantum memory for Gaussian states of light. The experiment also\nsheds new light on fundamental limits of sensitivity of the magneto-optical\nresonance method.",
