An anonymous reader writes from an article on UPI: Using a series of laser beams, a pair of German scientists teleported information without the transfer or matter of energy. "Elementary particles such as electrons and light particles exist per se in a spatially delocalized state," Alexander Szameit, a professor at the University of Jena, explained in a press release. Classical information is coupled using a process called "entanglement." "As can be done with the physical states of elementary particles, the properties of light beams can also be entangled," said research Marco Ornigotti. "You link the information you would like to transmit to a particular property of the light." Researchers used polarization to encode information within a laser beam, enabling the teleportation of information instantly and in its entirety without loss of time. Whereas quantum information and quantum systems describe particle properties that are inferred, classical information describes physical properties directly measured.
