Bell inequalities: experimentally proving quantum non-locality

In the fascinating universe of quantum mechanics, one of the major discoveries that challenges our intuitive understanding of reality is the violation of Bell inequalities. These inequalities, formulated by physicist John Stewart Bell in the mid-20th century, represent a crucial boundary between a local reality, based on hidden and deterministic variables, and the strange quantum … Read more

The EPR Paradox: Einstein versus Quantum Mechanics

The EPR paradox, conceived in the midst of the intellectual turmoil of the 1930s by Albert Einstein, Boris Podolsky, and Nathan Rosen, remains one of the most fascinating and controversial enigmas of modern physics to this day. This thought experiment, which seemed intended to criticize and challenge quantum mechanics, actually shed light on unsuspected depths … Read more

Quantum physics in simple terms

La physique quantique en termes simples

IN BRIEF Definition: Quantum physics is a set of theories developed in the 20th century to explain the behavior of atoms and particles. Scientific revolution: Considered one of the two great revolutions of the twentieth century, alongside the theory of relativity. Nature of interactions: It describes how energy is exchanged in discrete values called quanta. … Read more
