The concept of Alice and Bob communicating is back in the spotlight with quantum key distribution added to it. This team from the University of York developed a process which involves displacing the data detectors – the point where information must be read – to a location separate from the sender and receiver. Doing so reduces probability of a hacker attacking the device. See the layperson’s article at ScienceDaily and the original study at the Cornell University Library site.
