Scientists have successfully transmitted quantum data and conventional data through a single optical fiber for the first time.
Fiber-optic cables are composed of thin strands of glass or plastic fibers that carry data as infrared light pulses. These fibers transmit data through different color channels, with each corresponding to a specific wavelength of light. Creating hybrid networks is challenging because quantum data is often transmitted through fiber-optic cables using entangled photons.
"To make the quantum internet a reality, we need to transmit entangled photons via fibre optic networks," study co-author Michael Kues, head of the Institute of Photonics at Leibniz University Hannover, said in a statement."We also want to continue using optical fibres for conventional data transmission."
