The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub. Normally, vortices ...

New theoretical work suggests that the pattern of light emitted by atoms could be used to detect gravitational waves at ...

Scientists measured negative time in a quantum physics experiment using photons and rubidium atoms, calling it an unusual behavior.

Researchers in Germany and the UK are the first to entangle pairs of photons using a single atom. Their technique is based on an optical cavity containing one rubidium atom, and could provide a way to ...

In a classic physics experiment, scientists set up quantum entanglement between sunlight and light generated here on Earth. The researchers in China, the United States, Germany, and the United Kingdom ...

In case you didn't realize it, photons are tiny little bits of light. In fact, they're the smallest bit of light possible. When you turn on a lamp, gigantic numbers of photons spring from that bulb ...

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 ...

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 ...
