Fiber optic cables have long been the backbone of global communications, enabling the high-speed Internet that connects billions of people daily. Now, these same cables are being tested as conduits 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.

For quantum computing to take off, quantum networks need to be developed as well. This research shows how existing infrastructure can help.

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,

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.

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