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

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

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

Physicists at the Max Planck Institute have developed an efficient new method to drive the quantum entanglement of photons, and demonstrated it by entangling a record number of photons. The technique ...

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 ...

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 ...

We are taught that light behaves both like a particle and like a wave. We think of the photon as the particle form of light. Question: When a photon hits your eye as you look at the sky, or directly ...

Using photonic chips to control single photons in waveguides is a promising route to technologies based on the photons'quantum properties. The ability to measure entanglement on such chips is a key ...

Why do we call photons 'particles'? Aren't they all electromagnetic waves? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better ...

When bound together by a process called quantum entanglement, a set of six photons can withstand the hard knocks that ordinarily would erase quantum information, researchers have shown. Papers ...

Are your photons entangled? At present, the only indication we have that we are producing entangled photons is through the emission of photons with complementary wavelengths. The true proof of ...

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