Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more ...

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 ...

Atoms inside of an optical cavity exchange their momentum states by "playing catch" with photons. As the atoms absorb photons from an applied laser, the whole cloud of atoms recoil rather than the ...

Shuo Sun’s research studies light-matter interactions at the quantum limit where single photons can interact with single atoms. The strong atom-photon interactions lead to two important applications ...

For the first time, scientists at the University of Sydney and the University of Basel in Switzerland have demonstrated the ability to manipulate and identify small numbers of interacting photons – ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Researchers at The Grainger College of Engineering have made a major breakthrough toward building future quantum networks. In a paper published in the research journal Nature in September, researchers ...

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' ...
