While other research groups had successfully transmitted quantum information alongside classical data streams in simulations of the internet, Kumar’s team was the first to teleport a quantum state alongside an actual internet stream.

Quantum Teleportation Was Achieved Over The Internet For The First Time

In 2024, a quantum state of light was 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.
