Northwestern University Researchers Achieve Quantum Teleportation Over Busy Fiber Optic Cables for Quantum Internet

Dec 24, 2024, 01:40 AM

Researchers from Northwestern University have successfully demonstrated quantum teleportation over a fiber optic cable that was simultaneously carrying regular internet traffic. This advancement indicates that quantum and classical networks can now share the same fiber optic infrastructure without interference, potentially paving the way for the development of a quantum internet. Previous assumptions suggested that a significant amount of new cabling would be necessary to support fragile quantum signals, but this experiment challenges that notion by showing that quantum teleportation can indeed survive in busy internet cables.
