Physicists Teleport Quantum Information 30km Over Internet Network

American physicists at Northwestern University (NWU) successfully carried out the first-ever quantum teleportation over a conventional optical communication line, spanning 30 kilometers. The experiment took place while the line was actively transmitting regular internet traffic within the university network.

This achievement is significant, as it challenges traditional notions of what’s possible in quantum teleportation. NWU Professor Prem Kumar notes that their experiment “paves the way” for future networks that can use existing infrastructure to transmit data both classically and quantumly.

The 400-gigabit fiber optic line was used for the experiment, which showed a success rate of over 80% in teleporting particles. Quantum teleportation enables information exchange between entangled particles at any distance, a phenomenon previously utilized in optical fibers or satellite communications with specialized lines.

NWU’s breakthrough offers promising possibilities for future quantum communication advancements.
