Electromagnetically induced transparency is a quantum interference effect that permits the propagation of light through an otherwise opaque atomic medium; a ‘coupling’ laser is used to create the interference necessary to allow the transmission of resonant pulses from a ‘probe’ laser. This technique has been used to slow and spatially compress light pulses by seven orders of magnitude, resulting in their complete localization and containment within an atomic cloud. Here we use… 
Coherent control of optical information with matter wave dynamics
TLDR
It is demonstrated that a slow light pulse can be stopped and stored in one Bose–Einstein condensates and subsequently revived from a totally different condensate, 160 μm away; information is transferred through conversion of the optical pulse into a travelling matter wave.
Stationary pulses of light in an atomic medium
TLDR
This work describes and experimentally demonstrate a technique in which light propagating in a medium of Rb atoms is converted into an excitation with localized, stationary electromagnetic energy, which can be held and released after a controllable interval, offering new possibilities for photon state manipulation and nonlinear optical processes at low light levels.
Electromagnetically induced transparency with resonant nuclei in a cavity
TLDR
Electromagnetically induced transparency in the regime of hard X-rays is demonstrated, using the 14.4-kiloelectronvolt nuclear resonance of the Mössbauer isotope iron-57 (a two-level system), to establish the field of nuclear quantum optics.
Propagation and storing of light in optically modified atomic media
Coherent interactions of laser light with atomic ensembles allow one to modify dispersive properties of a medium and lead to new optical phenomena. Studies of the controlled light propagation and
Electromagnetically induced transparency with tunable single-photon pulses
TLDR
This work demonstrates the use of EIT for the controllable generation, transmission and storage of single photons with tunable frequency, timing and bandwidth and probes the spectral and quantum statistical properties of narrow-bandwidth single-photon pulses, revealing that their quantum nature is preserved under EIT propagation and storage.

Electromagnetically induced transparency : Optics in coherent media
Coherent preparation by laser light of quantum states of atoms and molecules can lead to quantum interference in the amplitudes of optical transitions. In this way the optical properties of a medium
Four-wave-mixing stopped light in hot atomic rubidium vapour
Digital signal processing, holography, and quantum and classical information processing rely heavily upon recording the amplitude and phase of coherent optical signals. One method for achieving
Optical vortices of slow light using a tripod scheme
We consider propagation, storing and retrieval of slow light (probe beam) in a resonant atomic medium illuminated by two control laser beams of larger intensity. The probe and two control beams act

TLDR
