TL;DR: The entanglement of two atomic-ensemble quantum memories via optical fibres, enabled by the use of cavity enhancement and quantum frequency conversion, is demonstrated over dozens of kilometres.

TL;DR: In this article, the authors used cavity enhancement to create bright atom-photon entanglement, and harness quantum frequency conversion to shift the atomic wavelength to telecom for long-distance communication.

TL;DR: In this article, the entanglement of three remote quantum memories via three-photon interference was achieved by employing laser-cooled atomic ensembles and making use of a ring cavity to enhance the overall efficiency of the memory.

TL;DR: The Hong-Ou-Mandel interference witnesses an entangled NOON state of the collective atomic excitations, and it is demonstrated its two times enhanced sensitivity to a magnetic field compared with a single excitation.

TL;DR: In this paper , the authors reviewed the current state of the art for generating entanglement of quantum nodes based on various physical systems such as single atoms, cold atomic ensembles, trapped ions, diamonds with nitrogen-vacancy centers, and solid-state host doped with rare-earth ions.
