Physicists from University of Vienna and Institute for Quantum Optics and Quantum Information managed to convey a swirling beam of light at a distance of three kilometers. According to them, they first managed to convey such rays at a greater distance in the open air. Previous research scientists showed that the swirling waves of a certain length can form the set of channels that will provide a substantial increase in the transmitted data. Then the scientists were able to transfer about 2.5 terabits of information (equivalent to a volume of about 66 DVD-ROM drive) in the second, but not by air, and through fiber.
