...current study slowed light to a stop by shining it on super-cooled gaseous rubidium atoms. The atoms were bathed in laser light while a second beam was shined through them. By adjusting the intensity of the beams, the "fingerprint" of the second beam was imprinted on the electrons of the super-cooled atoms. In that state, the light was standing still...
That "quantum fingerprint" was then converted back into light by again shining a laser on them. Usually, any information about light is destroyed when its photons are absorbed by atoms. In these studies, the information was preserved...
...secure computer network, and you keep your password on a Post-it note stuck to the monitor.
