Quantum Teleportation Achieved Over Active Internet Cables

Northwestern University researchers demonstrate quantum information transfer using existing fiber-optic networks, a breakthrough for quantum communication.

Scientists successfully performed quantum teleportation over a 30-kilometer fiber-optic cable already carrying regular internet traffic.
The experiment demonstrated that quantum and classical communications can coexist on the same infrastructure by carefully selecting light wavelengths and using noise-reducing filters.
Quantum teleportation relies on entangled particles to transfer information instantly, bypassing the need for physical travel of particles.
This breakthrough eliminates the need for specialized infrastructure, potentially accelerating the development of quantum computing, cryptography, and a quantum internet.
Future research will focus on extending the distance of teleportation, testing real-world underground cables, and achieving entanglement swapping for enhanced quantum applications.
