New work by an international group of scientists has for the first time made it possible to “beam” images over a network without physically sending the image itself.
Researchers from the University of the Witwatersrand in Johannesburg and the Institute of Photonic Sciences in Spain have used a cutting-edge technique that transmits images using an advanced form of “quantum communication”.
Scientists have used quantum optics to expand the “alphabet” to send more complex information, such as fingerprints or faces.
Instead of physically transmitting images, this new approach uses a “teleportation-inspired configuration”.
The teleportation-inspired nature of the message means that information does not physically travel between the parties, as it does with a smartphone or TV broadcast.
“STAR TREK” TECHNOLOGY BECOMES A REALITY
Professor Andrew Forbes of Wits University said, “Traditionally, two communicating parties physically send information from one to the other, even in the quantum realm. Now it is possible to beam information over the link. Star Trek technology has become a reality.”
The most important advance the scientists made was the use of a nonlinear optical detector in the study.
It eliminates the need for extra photons and, when used, can send any “pattern” such as a fingerprint or face.
According to Forbes, this protocol has all the characteristics of teleportation except for one key component. It needs a bright laser beam to make the non-linear detector operational.
One of the areas where this technology can be used today is banking.
Teleportation technology means that a customer can send their fingerprint to a bank without using any physical means. This makes it almost impossible for hackers to interfere with the process.
