A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

A stable graphene signal suggests some quantum particles can remember past interactions, a key step toward quantum computing.

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

When molecules collide with surfaces, a complex exchange of energy takes place between the molecule and the atoms composing the surface. But beneath this dizzying complexity, quantum mechanics, which ...

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

Schrödinger’s cat just got a little bit fatter. Physicists have created the largest ever ‘superposition’ — a quantum state in ...

The interior of the vacuum chamber during a scattering experiment. The detector is shown in grey (top right) and the Au(111) gold surface is shown in yellow. The lines indicate the path of the ...
