A quantum state of light has been successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.

Scientists accomplished quantum teleportation over busy internet lines, meaning special lines may not be required for quantum communication.

Q uantum teleportation has been demonstrated over a fiber optic cable carrying classical traffic (like the Internet) for the first time. The work suggests it will be possible to take advantage of the benefits quantum communication offers without needing to build a whole new infrastructure in parallel to what already exists.

In a development that reshapes the landscape of modern communication, researchers have successfully demonstrated quantum teleportation of information through existing fiber optic networks. Unlike the teleportation of objects often seen in science fiction,

Quantum teleportation, once confined to the pages of science fiction, is steadily becoming a tangible scientific achievement. Advances in quantum mechanics over the last decade have transformed teleportation from a theoretical concept into an experimental reality.

Scientists have quantified light scattering to find exact areas to place photons to keep them safe from other particles.
