Story summary

In 2024, researchers in the United States teleported a quantum state of light over 30 kilometers of fiber optic cable.
The work was led by Prem Kumar from Northwestern University.
The team used techniques to minimize light scattering, enabling quantum information to be transmitted alongside classical data without interference.
The findings were published in Optica.
