This research demonstrates entanglement distribution using Rb-87 atoms and photons over 24 km, suggesting advancements in quantum networks.
We demonstrate first steps toward atom-atom entanglement over 24 km of deployed fiber by distributing entanglement between a Rb-87 atom and a photon using quantum frequency conversion from 780 nm to low-loss telecom S-band.
