Half a meter of Teleportation
Professor Eugene Polzik and his team at the Niels Bohr Institute at the University of Copenhagen in Denmark, together with the Max-Planck Institut for Quantum Optics in Germany, have taken a major step forward in research on teleportation using light and matter.
During the experiment they managed to teleport a macroscopic atomic object (very small but visible to the human eye without a microscope) half a meter, although they believe that the distance could be greater.
“The teleportation of two simple atoms was already done two years ago, but at a distance of a fraction of a millimeter,” added Polzik.
“Our method allows teleportation between much greater distances, thanks to the use of light in the process,” he explained.
Juan Ignacio Cirac Sasturain, head of the German team and 2006 Prince of Asturias Award for Scientific and Technical Research, explains that “we managed to teleport the state
quantum of up to 500 photons to several billion atoms”.
“Thus, -he adds- compared to the teleportation experiments that have taken place so far (where the state of a few photons has been teleported to others, or that of a single atom to another) ours is the first to teleport the property from one object to another totally different (light to matter) and in which there is a large number of atoms and photons.”
