Quantum memories are an important component of quantum networks, serving much the same role as hard drives in today's computers. And the interest in storing quantum data efficiently and effectively is only growing, with practical applications including a quantum fibre-optic internet and other methods of secure communication.

"This experiment involved taking short pulses of light, in which we could encode quantum information, storing the light in the atoms, and then retrieving the original pulse that carries the same information," explained Saglamyurek.
