For years, researchers have tried to harness the "twist" of light to transmit data. This property describes how light spirals ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first.

Researchers in the Department of Electrical and Computer Engineering at the University of Illinois Urbana-Champaign have ...

Large-scale quantum communication networks require both reliable quantum memories and coherent single-photon sources that can exchange quantum information efficiently. A coherent source of single ...

ISTA physicists have confirmed a theory proposed 20 years ago that could advance quantum technology.

Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious, because in the world we see ...

Photographs can reveal things that are otherwise impossible for the naked eye to see, be they distant galaxies or microscopic ...

Quantum scientists in Innsbruck have taken a major leap toward building the internet of the future. Using a string of calcium ions and finely tuned lasers, they created quantum nodes capable of ...

In the classical world, a beam of light is a smooth, continuous wave. In the quantum realm, however, photons manifest as the discrete constituents (quanta) of light. These photons can be carefully ...
