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

In simple terms, quantum teleportation involves sending information from one place to another using something called "quantum entanglement".

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.

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.

However, a recent Northwestern University study has successfully demonstrated quantum teleportation over a fiber optic cable that also carries Internet traffic. The research opens the door to simpler infrastructure to enhance sensing technologies and quantum computing by enabling new quantum communication methods over existing Internet connections.

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,

Professor Prem Kumar and his team successfully transmitted quantum information through a fiberoptic cable carrying high-speed Internet traffic.

Northwestern University engineers are the first to successfully demonstrate quantum teleportation over a fiberoptic cable already carrying internet traffic.

Researchers at Northwestern University have achieved a significant milestone by successfully demonstrating quantum teleportation using a fiber optic cable that also carries regular Internet traffic. This innovation simplifies the potential integration of quantum and classical communications,

Quantum 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.
