Nanyang Technological University (NTU) Singapore and Osaka University scientists have built a Terahertz wireless chip using  photonic topological insulators. The chip can transmit terahertz (THz) waves resulting in a data rate of 11 Gigabits per second (Gbit/s), which is capable of supporting real-time streaming of 4K high-definition video, and exceeds the hitherto theoretical limit of ...
