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

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

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

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 ...

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

A long-standing physics mystery has been solved with the discovery of emergent photon-like behavior inside a strange quantum ...

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 ...

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 ...

Why does light carry energy even though it has no mass? This video explains the real physics behind photons, energy–momentum ...

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 ...

On and off: Better, simpler control of single-photon emissions opens the door to new platforms in quantum research. (Courtesy: art-skvortsova/iStockphoto) Researchers ...
