A pulse of light can be stopped, transported, and restarted again using a cloud of super-cold atoms, US researchers have shown.
The technique could ultimately be used for advanced computing devices or gravity detectors.
The experiments demonstrate physicists' increasing ability to manipulate light. Being able to control it in this way could be useful for optical or quantum computers, the team suggests.
