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

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

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

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

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of ...

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 ...

Scientists have revealed how quantum interference and symmetry dictate molecular behavior in collisions with gold surfaces, offering new insights into molecular interactions. The findings can have ...

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?

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