Antiferromagnetic materials allow for processing at terahertz speeds

Data hurtle down fiber-optic cables at frequencies of several terahertz. As soon as the data arrive on a PC or television, this speed must be throttled to match the data processing speed of the device components, which currently is in the range of a few hundred gigahertz only. Researchers have now developed a technology that can process the data up to hundred times faster and thus close the gap between the transport and processing speeds.
