German scientists successfully teleport classical information
"Elementary particles, such as electrons and light particles, exist per se in a spatially delocalized state," says Szameit. For these particles, it is with a certain probability, thus, possible to be in different places at the same time. "Within such a system spread across multiple locations, it is possible to transmit information from one location to another without any loss of time." This process is called quantum teleportation and has been known for several years.
To entangle properties of light beams
The researchers used a special form of laser beams in the experiment. "As can be done with the physical states of elementary particles, the properties of light beams can also be entangled," explains Marco Ornigotti, a member of Prof. Szameit's team. For physicists, "entanglement" means a sort of codification. "You link the information you would like to transmit to a particular property of the light," clarifies Ornigotti who led the experiments for the study that was now presented.
