“…Second, the resonant enhancement of the refractive index with vanishing absorption can be realized via quantum interference effects [37][38][39][40][41][42]. Although the maximum enhancement demonstrated experimentally in a gaseous medium is 10 −4 [43,44], there is good reason to expect much larger values, such as 10 −2 , for solid state materials [45,46]. It should be noted that manipulating refractive index either on the frequency of the quantum field to be stored or on the frequency of the strong control field should not only guarantee small losses but also no amplification.…”

Off-resonant Raman interaction of a single-photon wave packet and a classical control field in an atomic medium with controlled refractive index is investigated. It is shown that a continuous change of refractive index during the interaction leads to the mapping of a single photon state to a superposition of atomic collective excitations (spin waves) with different wave vectors and visa versa. The suitability of refractive index control for developing multichannel quantum memories is discussed and possible schemes of implementation are considered.
