A quantum network is just like a regular network, the one that you’re almost certainly connected to at this very moment. The only difference is that each node in the network is just a single atom (rubidium atoms, as it happens), and those atoms are connected by photons. For the first time ever, scientists have managed to get these individual atoms to read a qubit off of a photon, store that qubit, and then write it out onto another photon and send it off to another atom, creating a fully functional quantum network that has the potential to be expanded to however many atoms we want.
