Há 3 dias · That attitude began to change, however, in 1964 when the Northern Irish physicist John Bell figured out a way to distinguish the so-called hidden-variables models from no-frills quantum mechanics. All it needed was some serious thought – “There was nothing in Bell’s inequality that was not known to the quantum founders,” the authors say.
Entanglement is a fundamental aspect of quantum mechanics and has been experimentally confirmed in various systems, including photons, electrons, and atoms. The concept of entanglement was first introduced by Albert Einstein, Boris Podolsky, and Nathan Rosen in 1935, as part of their famous EPR paradox.
Há 6 dias · Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement.
