Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.

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

A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single ...

Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is. Featuring new ...

Quantum computers, systems that process information leveraging quantum mechanical effects, are expected to outperform ...

A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

By bringing the long-standing and opposing views of quantum mechanics together to form a single cohesive theory, a research ...

Physicists have coaxed particles of light into undergoing opposite transformations simultaneously, like a human turning into a werewolf as the werewolf turns into a human. In carefully engineered ...
