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 ...

Tiny 3D-printed “light cages” are giving researchers a new way to catch and hold individual particles of light on a chip, a ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Experts in nuclear physics and quantum information have demonstrated the application of a photon-number-resolving system to accurately resolve more than 100 photons. The feat is a major step forward ...

Seven billion years ago, three cosmic travelers set out together on an epic journey to Earth. They've just arrived, and they bring news of the great beyond. Their surprising story could overturn ...

The speed of light in a vacuum is 299,792,458 m s –1, right? Not necessarily, according to a team of physicists in the UK, which has found that the speed of an individual photon decreases by a tiny ...
