Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a superposition of states—being in multiple places and configurations all at ...

Quantum theory has long treated time as a silent backdrop, a parameter that never jitters even as particles flicker in and ...

Quantum state diffusion framework makes it possible to characterize quantum measurement in terms of entropy production ...

A microscopic clump of sodium has become the largest object ever to be observed as a wave, improving upon previous records by ...

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