Metal clusters made of thousands of atoms showed quantum interference, offering new insight into how large objects follow ...

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 ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

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

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?

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 ...

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 ...
