Quantum mechanics, or quantum physics, is the body of scientific laws that describe the wacky behavior of photons, electrons and the other subatomic particles that make up the universe.

The term "quantum mechanics" was first coined by Max Born in 1924. The acceptance by the general physics community of quantum mechanics is due to its accurate prediction of the physical ...

Einstein’s arguments culminated in the famous “EPR” paper that he wrote in 1935 with Boris Podolsky and Nathan Rosen, which supposedly proved that quantum mechanics could not represent reality ...

A century ago, physics had its Darwinian moment — a change in perspective that was as consequential for the physical sciences as the theory of evolution by natural selection was for biology.

Physicists John F. Clauser, Alain Aspect and Anton Zeilinger received the 2022 Nobel Prize in physics on Oct. 4, for their research in quantum mechanics. (Video: AP) By Joel Achenbach.

Whereas in classical physics, a particle such as an electron has a real, objective position and momentum at any given moment, in quantum mechanics, those quantities don’t, in general, ‘exist ...
