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.

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.

    I doubt that would be the eventual use case. This is more likely to be used to make sure no one has looked at data you have sent to a specific individual/party.
