Paper Abstract
A new developed for storing quantum information on atomic polaritons being at thermal equilibrium is developed
for the first time. We propose a new type of spatially periodic structure - polaritonic crystal (PolC) formed
by trapped two-level atoms interacting with quantum electromagnetic field in one-dimensional array of tunnelcoupled
microcavities, which allows polaritons to be fully localized. The quantum degeneracy and phase transition
to superfluid (Bardeen-Cooper-Schrieffer-type) state for low branch polaritons is discussed. The principal result is
that the group velocity of polaritons depends essentially on the order parameter of the system, i.e. on the average
photon number in the cavity array. An algorithm for the spatially distributed writing, storing, and retrieving of
quantum optical information using polariton wave packet propagated in the cavity array is examined. To take
into account decoherence processes in polaritonic system the quantum Brownian particle model is discussed as
well.
