The “dark photon” theory of light, as described in recent viral posts, is not a new particle and it does not overturn quantum mechanics. It is a way of describing interference by decomposing a photon’s quantum state into bright (detectable) and dark (undetectable) modes, a standard idea in quantum optics. This reinterpretation leaves Maxwell’s equations and quantum electrodynamics intact and makes the same experimental predictions as the usual wave–particle picture.

Researchers demonstrate that by shaping the spatial and temporal structure of photons, they can engineer customized quantum states suited for next-generation communication, sensing, and imaging technologies....

Il était acquis depuis 180 ans que l'effet Faraday dépendait seulement de la partie électrique de la lumière, mais une équipe israélienne vient tout juste de bousculer cette vieille hypothèse en montrant que le champ magnétique est tout aussi important.

Electron avalanche multiplication can enable an all-optical modulator controlled by single photons.

Wavefront shaping enables control of classical light through scattering media. Extending these techniques to spatially entangled photons promises new quantum ap

The race for quantum supremacy is evolving from a sprint into a marathon of engineering, with a clear focus shifting from simply increasing…
