The experiment involved for the first time a macroscopic atomic object containing thousands of billions of atoms. They also teleported the information a distance of half a meter but believe it can be extended further.
“Teleportation between two single atoms had been done two years ago by two teams but this was done at a distance of a fraction of a millimeter,” Polzik, of the Danish National Research Foundation Center for Quantum Optics, explained.
“Our method allows teleportation to be taken over longer distances because it involves light as the carrier of entanglement,” he added.
Quantum entanglement involves entwining two or more particles without physical contact.
