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,

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,

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

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.

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