Quantum physicists have measured negative time in a remarkable quantum experiment that is reshaping discussions around quantum mechanics, photon behavior, and the nature of time itself. The study, ...

Quantum optics, where light and matter interactions are examined at the microscopic level, has earned Nobel prizes—including three awarded since 2001—for some of science's biggest names. However, even ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

The vast majority of modern quantum technologies—from quantum cryptography to the quantum internet to the quantum computer—rely on one essential element: the transmission of photons. Two qubits (two ...

Hubble eXtreme Deep Field "XDF" (2012) view — except for a few stars, every speck of light is an entire galaxy — some as old as 13.2 billion years. NASA; ESA; G. Illingworth, D. Magee, and P. Oesch, ...

“Molecules” made from three photons have been created by physicists in the US. The photon triplets were made by firing laser light into an atomic gas and the researchers believe that their technique ...

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 ...

Slowing down: the Sun as seen by the SDO. (Courtesy: Solar Dynamics Observatory/NASA) Sunlight is slowing the rotation of the Sun’s outermost layers by stealing its angular momentum. That is the claim ...

Cross two flashlight beams and they pass right through one another. That’s because particles of light, or photons, are mostly antisocial — they don’t interact with each other. But now scientists have ...

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 ...
