Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

Electrons are usually described as particles, but in a rare quantum material, that picture completely breaks down ...

The quantum world has a reputation for being elusive, but physicists are now starting to watch it unfold in real time. For the first time, researchers have directly imaged the restless motion of atoms ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

In a study by TU Wien and FU Berlin, researchers have measured what happens when quantum physical information is lost. This clarifies important connections between thermodynamics, information theory ...

Photosynthesis and other natural processes depend on energy moving quickly and efficiently across molecules. When sunlight strikes a leaf, energy races across protein structures before it can be ...

Simmons says that silicon quantum processors offer an inherent advantage in scaling, too. Generating numerous registers on a ...

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...
