Photon–atom interactions in nanophotonic systems exploit the tight confinement of light in subwavelength structures to enhance and precisely engineer light–matter coupling at the single-quantum level.

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 ...

“Negative time” might sound like science fiction, but an international team of theorists and experimentalists has determined that a photon can, in fact, spend a negative amount of time in an excited ...

A new theory, that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon. A new theory, that explains ...

A team of physicists from the Faculty of Physics at the University of Warsaw, the Center for New Technologies at the University of Warsaw and Emory University (Atlanta, U.S.) analyzed how atoms' ...

A new platform developed by Illinois Grainger engineers demonstrates the utility of a ytterbium-171 atom array in quantum networking. Their work represents a key step toward long-distance quantum ...

Add Yahoo as a preferred source to see more of our stories on Google. Photons are massless quantum particles that form light. They travel at incredible speeds and interact with various forms of matter ...
