The physicists applied the theories of quantum teleportation to large-scale networks and successfully transmitted quantum information over fiber optics—cables through which standard Internet Protocol is transmitted—into a quantum memory device. Because it leverages existing infrastructure—the fiber optics—this experiment has large implications for developing quantum networks.

Fiber Optic Cables Could Offer Big Breakthrough in Data Security

Data is transmitted as light through fiber optics, however, and the wavelengths required for that transmission differ from those necessary in quantum memory storage. But the research discovered that a particle could be transmitted via fiber optics and another quantum particle could be stored in the quantum memory.

The breakthrough is very promising for data security, though there’s a lot more work needed to be done before quantum teleportation can be successful outside of a lab environment. But as more and more sensitive data becomes available on the Internet, there’s one thing that’s certain: The need for that data to be formidably protected continues to rise.
