Teleport information using laser beams

German scientists use lasers to teleport information from one point to another without changing matter and losing energy.

Teleportation has been demonstrated by scientists in the quantum world before. "Quantum particles like electrons and light particles exist in an uncertain spatial state," explains Alexander Szameit, a professor at the University of Jena in Germany.

In other words, these particles can be in two or more places at the same time with a certain probability. "In a space spread over many locations, these particles can transmit information from one place to another at the same time," Professor Szameit said in the study published on January 11 in the journal Laser & Photonics Reviews.

According to UPI, in the latest experiment, the teleportation technique was successfully applied to transmit classical physics information. Researchers were able to use quantum particles to teleport the necessary information through a complex process called "quantum entanglement".

“Similar to the physical states of elementary particles, the properties of a light beam can also be intentionally linked,” explains Marco Ornigotti, co-author of the study. “This allows you to associate the information you want to convey with a specific property of the light.”

Specifically, the property of light that the researchers used in this experiment is polarization to encode information in the laser beam. The information encoded in the polarization of light is instantly transferred to another location without loss or distortion.
