Abstract

Using cold and ultracold rubidium atoms controlled with lasers intense enough to put the system into the Autler-Townes regime, fast, efficient, and broadband storage and manipulation of photonic signals is achieved. In demonstrating single-photon-level operation, signals are read out with exceptionally low-noise, which is inherent to this method. Finally, high efficiency and longer storage times are made possible by using Bose-condensed samples as the storage medium.
