When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

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

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

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

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 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 ...

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