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

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

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Scientists at Sandia National Laboratories and the Max Planck Institute have developed a way to produce a web of quantum entangled photons using a far more simple setup than usual. The key is a ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some ...

Physicists at the Max Planck Institute have developed an efficient new method to drive the quantum entanglement of photons, and demonstrated it by entangling a record number of photons. The technique ...

A long-standing physics mystery has been solved with the discovery of emergent photon-like behavior inside a strange quantum material. The finding confirms a true 3D quantum spin liquid and unlocks a ...

Physicists in Israel are the first to entangle five photons in a NOON state – the superposition of two extreme quantum states. Unlike previous schemes for creating such states, the researchers claim ...

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up ...

The ATLAS Collaboration observed photons elastically scattering from other photons — an effect predicted by quantum electrodynamics over 80 years ago. Because the coupling at each photon–charged ...

Remarkably, the physics of the Josephson effect, describing the tunnel coupling of the two superconductors, dictates that photons within the same junction strongly interact with one another, in sharp ...
