First Teleportation From One Macroscopic Object to Another
These guys have teleported quantum information from ensemble of rubidium atoms to another ensemble of rubidium atoms over a distance of 150 metres using entangled photons. That's the first time that anybody has performed teleportation from one macroscopic object to another.
“This is interesting as the first teleportation between two macroscopic-sized objects at a distance of macroscopic scale,” say Xiao-Hui and co.
Quite right. The goal in a quantum internet is that ensembles of atoms will sit at the heart of quantum routers, receiving quantum information from incoming photons and then generating photons that pass this information on to the next router.So clearly the first teleportation from one of these hearts to another is an important advance.
