Temporal cloak erases data from history : Nature News & Comment

 

If you’ve ever wanted to edit an event from your history, then help may soon be at hand. Electrical engineers have used lasers to create a cloak that can hide communications in a ‘time hole’, so that it seems as if they were never sent. The method, published today in Nature1, is the first that can cloak data streams sent at the rapid rates typically seen in telecommunications systems. It opens the door to ultra-secure transmission schemes, and may also provide a way to better shield information from noise corruption.
