Abstract
We consider a new approach to the storage of quantum information by macroscopic atomic excitation of two-level atomic systems. We suggest an original scheme of quantum cloning of an optical field into cavity polaritons containing a phase-insensitive parametric amplifier and an atomic cell placed in the cavity. The high temperature quasi-condensation (and/or condensation) phenomenon for polaritons arising in the cavity under certain conditions is discussed for the purpose of storage of quantum information.
