Numerical simulations of the trapping and the retrieval processes of three different types of single-pulse photonic packets in a medium with electromagnetically induced transparency (EIT) are performed, and the simulation results for a single-Gaussian-pulse photonic packet correspond to the results of a recent well-known experiment. According to the simulation results, in spite of the fact that all three types of photonic packets, in general, experience a shape-preserving storage process, the single-Gaussian-pulse photonic packet suffers the least distortion. Also, based on our numerical simulation, we present, for the first time to the best of our knowledge, a shape- and quantum-state-preserving propagation of a multiple-Gaussian-pulse photonic packet in a medium with EIT. According to the simulations, attainment of a quantum random access memory (RAM) for photonic packets is within the bounds of possibility.
