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

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

Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that ...

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

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

Quantum mechanics can explain and recover classical results under some specific approximations. However, deriving quantum mechanical results strictly from classical assumption is generally not ...

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 ...

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

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 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 ...
