This is entangling two atoms (two atom-photon pairs are created and then the two photons are entangled together). The Chinese record is for photons only. > While photons have been entangled over great distances before, this study marks a new distance record for entangling two atoms, which could function as “quantum memory” nodes, over fiber optics.
