Researchers at Southeast University's National Key Laboratory for Millimeter Waves, with Nanjing University and Hong Kong University of Science and Technology, demonstrated an insulator-free topological photonic waveguide that enables multichannel routing of topological photons. The structure is presented as a key enabling technology for next‑generation photonic quantum computing, high‑speed optical communications and highly integrated photonic integrated circuits; results published in Nature on
