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

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 ...

A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to ...

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 ...

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

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 ...

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 working on CERN’s Compact Muon Solenoid (CMS) experiment have published the latest data in their search for a long-lived exotic particle known as the dark photon. Dark photons (also called ...

Experts in nuclear physics and quantum information have demonstrated the application of a photon-number-resolving system to accurately resolve more than 100 photons. The feat is a major step forward ...

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

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 ...

For governments and corporations in the business of transmitting sensitive data such as banking records or personal information over fibre optic cables, a new system demonstrated by University of ...
