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...
