Light is usually treated as something simple, a clean beam that either shines or does not. At the quantum level, however, ...

Due to the inhomogeneity of biological tissue and the impact between photons and microscope particles, photons are inevitably scattered and diverged from the incident direction when traveling in the ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light — photons — on a silicon chip to make a major advance towards long-sought-after ...

For years, physicists treated an Earth-to-space quantum uplink as a beautiful idea that nature simply would not allow. Now a ...

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors. This form of nonlinear photonics could ...

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 ...

The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible ...

Photons carry the electromagnetic force, and act as both particles and waves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Photons are ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...
