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

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

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 ...

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

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

Google claims to have achieved a verifiable quantum breakthrough with a new algorithm that outperforms the most powerful ...

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 ...
