Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource ...

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 ...

Ghost imaging is like a game of Battleship. Instead of seeing an object directly, scientists use entangled photons to remove the background and reveal its silhouette. This method can be used to study ...

It's a glimpse of science fiction made fact: Scientists have created a new form of light that could someday be used to build light crystals. But before would-be Jedis start demanding their sabers, the ...

The spectral manipulation of photons is essential for linking components in a quantum network. Large frequency shifts are needed for conversion between optical and telecommunication frequencies, while ...
