* ICFO researchers report in
Nature on having achieved, for the first time, entanglement of two multimode quantum memories located in different labs separated by 10 meters, and heralded by a photon at the telecommunication wavelength.
* The scientists implemented a technique that allowed them to reach a record in the entanglement rate in a system that could be integrated into the fibre communication network, paving the way to operation over long distances.
* The results are considered a landmark for quantum communications and a major step forward in the development of quantum repeaters for the future quantum internet.
