Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

The theory of Quantum Chromodynamics (QCD) underpins our understanding of the strong interaction, governing how quarks and gluons interact to form hadrons. One of the most promising nonperturbative ...

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

A chip-scale interface entangles light and electronic states without cryogenic cooling, bringing quantum networking hardware ...

In the classical world, a beam of light is a smooth, continuous wave. In the quantum realm, however, photons manifest as the discrete constituents (quanta) of light. These photons can be carefully ...

Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves are generated under specific interactions. Light also bends around corners, ...

Quantum computers will break encryption one day. But converting data into light particles and beaming them around using thousands of satellites might be one way around this problem. When you purchase ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...

Quantum entanglement is often described as a mysterious link between particles, but new research shows it may be even richer ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.
