Physicists at the University of Bath in the UK have developed a new kind of fiber designed to enhance the robustness of networks. This robustness could prove to be especially important in the coming age of quantum networks. The team has fabricated optical fibers that can protect light using the mathematics of topology. Best of all, these modified fibers are easily scalable, meaning the structure of each fiber can be preserved over thousands of kilometers.
