A new turn on quantum communication in optical fiber

New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting ramifications for secure information transfer across optical fiber networks. The group has exhibited that different quantum patterns of twisted light can be transmitted over an ordinary fiber link that, incomprehensibly, supports just one pattern. The suggestion is a new way to deal with realizing a future quantum network, harnessing different dimensions of entangled quantum light. Science Advances published the research by a group led by Professor Andrew Forbes from the School of Physics at Wits University in collaboration with a foreman by Professor Jian Wang at HUST. In their paper, titled "Multi-dimensional entangle...
