Coherent control of optical information with matter wave dynamics
Article Abstract:
The experiments have shown that a slow light pulse can be stopped and stored in one Bose-Einstein condensate (BEC) and subsequently revived from a totally different condensate, where the information is transferred through conversion of the optical pulse into a traveling matter wave. The results have provided a demonstration of coherent optical information processing with matter wave dynamics, which can be used in quantum information processing and wavefunction sculpting.

Light speed reduction to 17 metres per second in an ultracold atomic gas
Article Abstract:
Electromagnetically induced transparency allows the propagation of light pulses through opaque medium. This has been demonstrated in an ultracold gas of sodium atoms where optical pulses propagate 20 million times slower than the speed of light in a vacuum. An inferred nonlinear refractive index of 0.18 squared cm W(super-1) is reported, and large optical nolinearities are exhibited.

Observation of coherent optical information storage in an atomic medium using halted light pulses
Article Abstract:
Research is presented concerning the use of electromagnetic transparency to halt the movement of laser pulses within a cloud of cold, magnetically trapped sodium atoms. The benefits of this research for quantum information processing are discussed.
