Northwestern University engineers have made a groundbreaking advancement in quantum communication by successfully demonstrating quantum teleportation over a fiber optic cable that is simultaneously carrying Internet traffic.

This innovative achievement, published in the journal Optica, opens up new possibilities for integrating quantum communication with existing Internet infrastructure, potentially simplifying the setup required for distributed quantum sensing and computing applications.

Leading the study, Professor Prem Kumar expressed his excitement, stating, “This is incredibly exciting because nobody thought it was possible. Our work shows a path towards next-generation quantum and classical networks sharing a unified fiber optic infrastructure.”

WHAT IS QUANTUM TELEPORTATION?

Quantum teleportation is a process by which quantum information (such as the exact state of a particle) is transmitted from one location to another without physically moving the particle itself. Instead, the information is "transferred" using the principles of quantum mechanics, particularly quantum entanglement.

This concept has nothing to do with teleporting physical objects or people as in science fiction; it is about the transmission of quantum states.

The researchers tackled the challenge of transmitting delicate quantum signals alongside millions of classical data particles without interference. They identified specific wavelengths within the fiber that minimized scattering and employed advanced filters to reduce noise from regular Internet traffic.

To validate their method, the team set up a 30-kilometer-long fiber optic cable with a photon at each end. They successfully transmitted quantum information while also handling high-speed Internet traffic, demonstrating that quantum teleportation can function effectively even in busy communication environments.

This research marks a significant step toward realizing practical quantum networks capable of secure communication across extensive geographic areas.

Wonder how it could be useful in daily lives not taking into account military uses. No lag in phone over ip maybe?

Something big is missing from this news.

If what they say is true, and they were able to transfer information using entangled particles, that means,
1. circumnavigated Heisenberg uncertainty principle.
2. they changed the state of entangled particles without breaking entanglement.
3. exceeded the speed of Causality.

I call BS.
