Transmitting analog video via photons is old hat: that’s how everything started, after all, back in the day with over-the-air TV. Up the frequency of those photons from radio to visible ...

The nature of quantum particles has long puzzled scientists. While single-particle interference suggests that a photon can behave like a spread-out wave, a whole photon is only ever detected in one ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University of Iowa researchers found that unwanted photons produced by lasers can be ...

In a classic physics experiment, scientists set up quantum entanglement between sunlight and light generated here on Earth. The researchers in China, the United States, Germany, and the United Kingdom ...

Collide light with light, and poof, you get matter and antimatter. It sounds like a simple idea, but it turns out to be surprisingly hard to prove. A team of physicists is now claiming the first ...
