Abstract: The talk will be focused on our recent progress in realization of quantum memory using electromagnetically induced transparency (EIT). For the first time storage and retrieval of a squeezed vacuum state in atomic rubidium atoms was demonstrated. The retrieved light retains quadrature squeezing, albeit degraded by absorption and atomic decoherence. Time-domain homodyne tomography allowed to perform full characterization of input and retrieved states, obtain density matrices of both ensembles and evaluate the memory fidelity.
