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.

Information storage and transfer in the manner of simple ones and zeros — as in today’s classical computer technologies — is insufficient for quantum technologies under development. Now, researchers from Japan have fabricated a nanoantenna that will help bring quantum information networks closer to practical use.

In a study recently...
