Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin ...

You can’t divide the indivisible, unless you use quantum mechanics. Physicists have now turned to quantum effects to split phonons, the smallest bits of sound, researchers report in the June 9 Science ...

Quantum mechanics is simultaneously beautiful and frustrating. Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

A conjecture called superdeterminism, outlined decades ago, is a response to several peculiarities of quantum mechanics: the apparent randomness of quantum events; their apparent dependence on human ...

Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger's cat analogy, ...

On the centennial of modern quantum mechanics, the Nobel Committee awarded the year’s most prestigious physics prize to an experiment that demonstrated how quantum effects play out on large ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...
