Abstract

A protocol, which essentially increases the efficiency of the quantum memory based on the atomic frequency comb (AFC), is proposed. It is well known that a weak short pulse, transmitted trough a medium with a periodic structure of absorption peaks separated by transparency windows (AFC), is transformed into prompt and delayed pulses. Time delay is equal to the inverse value of the frequency period of the peaks. It is proposed to send the prompt pulse again through the medium and to make both delayed pulses to interfere. This leads to the essential increase of the efficiency of the AFC storage protocol.
