Since Charles Bennett and his team first proposed quantum teleportation in 1993, science fiction enthusiasts have had to be content with frustratingly prosaic examples of the principle. However, at the University of Copenhagen in Denmark, physicists have passed a milestone that will help to bring some practical applications of teleportation within sight (Nature 443 557). Glowing caesium “This is the first time teleportation has been achieved between the ‘flying’ medium of light and the ‘stationary medium’ of atoms,” said Eugene Polzik of Copenhagen. “Such teleportation could serve as a main building block of a quantum network connecting distant quantum processors.” Quantum teleportation cleverly evades one of the best known peculiarities of quantum states – their inability to be measured precisely. Only some of the information of a quantum state can be learned in a single measurement, and once that measurement is made, the quantum state is effectively destroyed.
