Beyond the adiabatic approximation, we develop a quantum theory for optical probe pulses propagating in electromagnetically-induced-transparency media. With the introduction of Lengevin noise
operators, theoretical results on the degradation of quantum noises give agreement to the experimental realizations in the slow light [D. Akamatsu et al., Phys. Rev. Lett. 99, 153602 (2007)], as well as storage and retrieval [K. Honda et al., Phys. Rev. Lett. 100, 093601 (2008)], for a squeezed vacuum pulse.

Keywords: electromagnetically induced transparency, squeezed light, storage and retrieval
