Researchers demonstrate that by shaping the spatial and temporal structure of photons, they can engineer customized quantum ...

The parametric interaction of light beams in nonlinear materials is usually thought to be too weak to be observed when the fields involved are at the single-photon level. However, such single-photon ...

Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

Physicists successfully teleport quantum information between photons from different sources, a key step towards a secure ...

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 ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

Seven billion years ago, three cosmic travelers set out together on an epic journey to Earth. They've just arrived, and they bring news of the great beyond. Their surprising story could overturn ...

Physicists have created a new kind of light by chilling photons into a blob state. Just like solids, liquids and gases, this recently discovered condition represents a state of matter. Called a ...

This massive particle could serve as the connection between dark matter and the everyday matter that comprises stars, planets and us. When you purchase through links on our site, we may earn an ...

A gas made of particles of light, or photons, becomes easier to compress the more you squash it. This strange property could prove useful in making highly sensitive sensors. While gases are normally ...
