Researchers say they have found a way to teleport images through the network without touching them.
An international team of experts from the University of the Witwatersrand (South Africa) and the Institute of Photonic Sciences (Spain) teleported the images using laser light models receiving optical detectors and handling quantum processes. The rules of quantum physics allow the image’s information to be displayed at the terminal without physically moving from the sending device, according to research team leader Professor Andrew Forbes of Wits University.
The above achievement is just one potential aspect of quantum communications, an emerging scientific field that allows data to be transmitted over far greater distances than existing telecommunications systems.
In 2017, Chinese scientists caused a stir when they demonstrated that they could instantly transport a photon from the ground to a satellite in earth orbit 1,400km away.
With the latest breakthrough, South African and Spanish researchers continue to expand the potential of the new field but warn that bad actors can exploit this technology to copy information in transit.
“We need to be careful because the new feature cannot prevent a sender from trying to cheat and send additional copies of information that are better than the teleported version. That means we can fall into the situation of sending out many copies of the character “Mr. Spock” as in Star Trek, if that’s what the character “Scotty” wants”, according to Dr. Adam Vallés of the Institute of Photonic Sciences. The research on teleportation was published in the journal Nature Communications.
