A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

In a significant step toward realizing the vision of quantum networks, a University of Illinois Urbana-Champaign (UIUC) research team has achieved a critical breakthrough. Quantum communication relies ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...
