One of the most common implementations of photonic quantum memories in ensemble systems such as atomic vapors involves a Lambda-type energy level scheme. The photonic quantum state to be stored is mapped to a long-lived excitation via a two-photon Raman transition mediated by a strong control field. In this context we present our experimentally-motivated theoretical work on optimization of quantum memory efficiency, the sensitivity of the memory efficiency to fluctuations of experimental parameters, and our experimental implementation of a THz-bandwidth quantum memory in hot atomic barium vapor.
