We consider a vacuum to be the lowest energy state of the Universe. But it's possible that there's an even lower-energy, more ...

A leading physicist argues the brain may operate like a quantum system—and that enhancing it could create humans who perceive ...

A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model ...

A novel approach for realizing the one-way quantum synchronization of phonons has been proposed by three theoretical ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades in the making, could help physicists probe the relationship between quantum ...

A new method reveals hidden order in quantum systems, potentially transforming how they are measured and used.

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

Over the last few years, optical atomic clocks have broken record after record in precision timekeeping. Atoms are cooled to ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it ...

Researchers have developed a way to flip time to move backward in a quantum system. This level of control could lead to ...

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 ...
