Studying the effect of fluctuating environment on intra-atomic frequency comb based quantum memory

Abstract In this article, we study the effect of various environmental factors on intra-atomic frequency comb (I-AFC) based quantum memory. The effect of the environment is incorporated as random fluctuations and non-uniformity in the parameters such as comb spacing and the optical depth, of the fre...
