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

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

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

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

Researchers have uncovered a method to purify a photon stream that is central to quantum circuitry. University of Iowa ...

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 ...

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