Antiferromagnetic-Based Memory Processes Data at Terahertz Speeds
Data travels down fiber-optic cables at frequencies of several terahertz. As soon as the data arrives on a PC or television, this speed must be throttled down to match the data processing speed of the device components; this speed currently is in the range of a few hundred gigahertz...

Faster Photons Could Make Data Totally Secure
Transferring data using light passed along fiber optic cables has become increasingly common over the past decades, but each pulse currently contains millions of photons. That means that in principle, a portion of these could be intercepted without detection. Secure data is already encrypted, but if an...
