Two cups of warm water don't make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

A new solid-state material from Kyushu University turns visible light into high-energy UV at sunlight intensity. By attaching alkyl chains to the sp³ carbon atoms of an organic molecule, the ...

Novel source for quantum optics experiments could enable experiments in space or other locations with limited electricity ...

Replacing the crystal used for generating entangled photons can significantly increase quantum imaging contrast.

In a new theoretical study, physicists at the University of Oslo modeled a single photon meeting an ultrafast optical shutter ...

A new study shows that a solar sail may face drag force from the very light that powers it.

As far as particles of light are concerned, the collective is more important than the individual. When they get to decide between two states, they will favor the one that many of their fellow ...

Did light shine in the universe’s earliest moments, or was it hidden from view? While this question may seem simple at first, arecent article by Live Sciencereveals that the reality is far more ...

Entanglement between particles is a basic concept of quantum sciences. The ability to produce entangled particles in a controllable manner is essential for any quantum technology. Entanglement between ...
