... While lights are the fastest and the most robust carriers of information, it is difficult to localize and store them. Recently, a novel scheme to store the photonic information in an atomic ensemble was proposed [1], which is based on the phenomenon of ultraslow light propagation [2]. Ultraslow ligh ...
