Quantum memory is essential for the development of many devices in quantum information
processing, including a synchronization tool that matches various processes within a …

We report on the experimental demonstration of an optical spin-wave memory, based on the
atomic frequency comb (AFC) scheme, where the storage efficiency is strongly enhanced by …

We review a series of quantum memory protocols designed to store the quantum information
carried by light into atomic ensembles. In particular, we show how a simple semiclassical …

We explore optical coherence and spin dynamics of an isotopically purified 166 Er: 7 LiYF 4
crystal below 1 K and at weak magnetic fields< 0.3 T. Crystals were grown in our lab and …

We performed high-resolution magneto-optical spectroscopy of the hyperfine transitions
from I 15/2 4 to the I 13/2 4 and I 9/2 4 multiplets of Er 3+ 167 and Er 3+ 166 in an …

We show that a set of optical memories can act as a configurable linear optical network
operating on frequency-multiplexed optical states. Our protocol is applicable to any quantum …

The precise control of atom–light interactions is vital to many quantum technologies. For
instance, atomic systems can be used to slow and store light, acting as a quantum memory …

Vector beams have drawn considerable interest recently because of their unique properties
in the transverse plane. Here we experimentally realize optical storage of a vector beam of …

A scheme of photon echo-based quantum memory in the optimal optical QED cavity with off-
resonant Raman atomic transition is proposed. The scheme employs the atomic ensembles …
