“…Physically, quantum properties of atomic system coupled with e.m. field, can be described in terms of "bright" (optical branch) and "dark" (atomic branch) polaritons, being the two solutions of the problem in the terms of linear superposition of quantized optical field and atom excitation states -see Refs. [4,8] for more details. But existence of polaritons is not sufficient especially for quantum storage and transfer of information by some quantum memory device, and specific properties of quantum state become more important in the case -see Ref.…”

We consider a new approach for storing quantum information by macroscopic atomic excitations of two level atomic system. We offer the original scheme of quantum cloning of optical field into the cavity polaritons containing the phase insensitive parametrical amplifier and atomic cell placed in the cavity. The high temperature quasi-condensation (and/or condensation) phenomenon for polaritons arising in the cavity under the certain conditions is proposed for the first time.

“…The fact corresponds to electromagnetically induced ampliˇcation of light. Simultaneously, the conditions for negative cubic nonlinearity evidence are determined which is of practical signiˇcance in problems of nonclassical light generation [13]. However, observation in experiment of considered regimes is under question due to probeˇeld linear absorption and the medium dispersive effects development.…”

Based on advanced quantum theory for the Λ-scheme nonlinear interaction of opticalˇelds in atomic BoseÄEinstein condensate, the regimes of giant negative nonlinearity and absorption coefˇcients have been obtained for a probe light pulse. The nonlinear laser ampliˇer setup (under the Λ-scheme realization) for generation of the quadrature-squeezed light is presented.Ha o¸´μ¢e ±¢ ´Éμ¢μ°É¥μ·¨¨¤²Ö¸Ì¥³Ò´¥²¨´¥°´μ£μ ¢ § ¨³μ¤¥°¸É¢¨Ö μ ¶É¨Î¥¸±¨Ì ¶μ²¥°¢ Éμ³-μ³ ¡μ §¥-Ô°´ÏÉ¥°´μ¢¸±μ³ ±μ´¤¥´¸ É¥ ¶μ± § ´ ¢μ §³μ¦´μ¸ÉÓ ·¥ ²¨ § Í¨¨·¥¦¨³ ¸£¨£ ´É¸±¨³μ É·¨Í É¥²Ó´Ò³¨ §´ Î¥´¨Ö³¨´¥²¨´¥°´ÒÌ ¶μ± § É¥²Ö ¶·¥²μ³²¥´¨Ö¨±μÔËË¨Í¨¥´É ¶μ£²μÐ¥´¨Ö ¶·μ¡´μ£μ¨³ ¶Ê²Ó¸ ¸¢¥É . ·¥¤²μ¦¥´ ¸Ì¥³ ´¥²¨´¥°´μ£μ ² §¥·´μ£μ Ê¸¨²¨É¥²Ö (´ μ¸´μ¢¥¸Ì¥³Ò ¢ § ¨³μ¤¥°¸É¢¨Ö)¸¢μ §³μ¦´μ¸ÉÓÕ £¥´¥· Í¨¨±¢ ¤· ÉÊ·´μ-¸¦ ÉÒÌ¸μ¸ÉμÖ´¨°¸¢¥É .

In the paper we consider a new approach for storage and cloning of quantum information by three level atomic (molecular) systems in the presence of the electromagnetically induced transparency (EIT) effect. For that, the various schemes of transformation into the bright and dark polaritons for quantum states of optical field in the medium are proposed. Physical conditions of realization of quantum nondemolition (QND) storage of quantum optical state are formulated for the first time. We have shown that the best storage and cloning of can be achieved with the atomic ensemble in the BoseEinstein condensation state. We discuss stimulated Raman two-color photoassociation for experimental realization of the schemes under consideration.
