TLDR
In this paper, a hybrid semiconductor-atomic interface was proposed to slow down a single photon emitted from a quantum dot by 15 times its temporal width, which is attractive for the implementation of quantum memories and quantum repeaters.Abstract:
Combining semiconductor quantum dots and atomic systems allows the light emitted from a quantum dot to be temporarily stored. Here, scientists describe a hybrid semiconductor-atomic interface that can slow down a single photon emitted from a quantum dot by 15 times its temporal width. The findings are attractive for the implementation of quantum memories and quantum repeaters.read more

Observation of electromagnetically induced transparency.
TL;DR: In this paper, the authors report the first demonstration of a technique by which an optically thick medium may be rendered transparent by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.
