Researchers, led by Professor Andrew Forbes from Wits University, have successfully used light to teleport images across a network without having to physically send them, similar to what you’ve seen in Star Trek. In other words, they used a teleportation-inspired configuration so that the information does not physically travel between the two communicating parties.
This new method consisted of entangled photons and a nonlinear optical detector, which enabled them to overlap a photon sent by the receiver with the information to be transmitted. The result? Information appearing at the receiver’s end as if it had been teleported there, without the need for physical travel between sender and receiver.

We hope that this experiment showing the feasibility of the process motivates further advances in the nonlinear optics community through pushing the limits towards a full quantum implementation. We have to be cautious now, as this configuration could not prevent a cheating sender from keeping better copies of the information to be teleported, which means we could end up with many Mr Spock clones in the Star Trek world if that is what Scotty wanted,” said Dr Adam Vallés from ICFO (Barcelona).
