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?

Albert Einstein was right about a shocking among of things, but not necessarily everything.

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, ...

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

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

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 ...
