Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, ...

A breakthrough experiment led by a team from the University of Stuttgart in Germany brings a quantum internet a step closer, ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic ...

Researchers at the University of Stuttgart have successfully teleported quantum states between photons from two distant light sources, marking a pivotal advance toward practical quantum repeaters.

Photons weaken in optical fibers, and unlike classical light, quantum information cannot be copied or amplified. Quantum ...

In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for ...

A new method could help scientists shed light on the universe’s most mysterious substance by narrowing down the hunt for a particular dark matter candidate — hidden "dark photons." Dark matter ...

Those of us who grew up watching Luke and Leia on screen have probably wondered at one point or another why we don’t have lightsabers. The basic reason why is because the photons that make up light do ...

A high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays, researchers have shown theoretically and experimentally.

Ordinarily, photons—particles of light—don't interact with each other. They interfere, but that's a characteristic that doesn't alter their wavelength or cause them to attract or repel. However, if ...

Up until the mid-20 th century, light was pretty ordinary. Yes, it was both a particle and a wave, but it didn’t do anything very weird. Then scientists, under-employed after the end of World War II, ...

Photons, the elementary particles that make up light, are known to be fast, weightless and to not interact with each other. But in new experiments, physicists at MIT and Harvard have now created a new ...
