Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...
Fiber uses fiber-optic lines that transmit data at the speed of light, whereas cable uses coaxial cables, which are traditionally used for TV service. Fiber typically offers faster upload and download ...
The race to build a quantum internet has shifted from theory to engineering, as researchers learn how to send fragile quantum ...
