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 ...

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

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 ...

Light is the workhorse of quantum technology, but in the real world it is messy, noisy and full of unwanted fluctuations that ...

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 ...

Research shows twisting light-matter coupling can unlock unusual topological phenomena, advancing nanophotonics and quantum ...

Photon purity is more than a technical detail. In photonic quantum computing, orderly single-photon streams are easier to ...

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, ...

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 ...

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

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