(Phys.org)—A team of engineers at Purdue University has succeeded in building a time cloak based on dual laser broadcast communications channels sent through a common medium. In their paper published in the journal Optica, the team describes how they improved on earlier work to create a time cloak that allows for hiding data in high-speed data communications.
