Demonstration of an atomic frequency comb quantum memory using velocity-selective pumping in warm alkali vapour

Abstract:

We present the first demonstration of velocity-selective pumping in an atomic vapour to preserve light-matter coherence. Control is illustrated by a subsequent demonstration of an atomic frequency comb quantum memory realised in the vapour.
