A nanoantenna for long-distance, ultra-secure communication: Researchers have improved the transfer efficiency between quantum information carriers, in a manner that's based on well-established nanoscience and is compatible with upcoming advanced communication technologies

Researchers have used a nanoantenna to focus light onto a single semiconductor nanobox. This approach will enhance the utility of quantum repeater technology currently under development for advanced communication and data storage. Such technology is essential to overcoming the limitations of classical computer information for securely sharing information over long distances.
