Abstract

Solid quantum memory progress Harnessing entanglement between light and material systems is of interest for future quantum information technologies. Two groups report advances in the development of the light–matter quantum interface that could pave the way for the construction of multiplexed quantum repeaters for long-distance quantum networks. Clausen et al. demonstrate entanglement between a photon at the telecommunication wavelength (1,338 nanometres) and a single collective atomic excitation stored in a neodymium-doped Y2SiO5 crystal. Saglamyurek et al. use a thulium-doped LiNbO3 waveguide to achieve a similar entanglement.
