Abstract

A trick of the light The cover graphic represents a remarkable experiment. A light pulse stopped and extinguished in one box is revived from a completely different box in a separate location and sent back on its way. In the actual experiment, a slow light pulse was stopped and stored in one Bose–Einstein condensate (the first 'box'), then revived from a different condensate, 160 μm away. Information was transferred by converting the optical pulse into a travelling matter wave more amenable to manipulation than light. The experiment (video streams of which can be seen online) shows that the interaction of resonant laser fields with Bose-condensed atom clouds is a powerful way of manipulating light with matter, and vice versa. Such quantum control may find application in quantum information processing and the controlled sculpting of atomic wavefunctions.
