Bell's theorem, Bell’s test
violated in Quantum Mechanics
quantum mechanics is incompatible with local realism
local realism을 테스트하는 방법으로 사용되며 이는 한 지점에서 발생한 물리적 과정이 다른 지점에서 빠른 속도로 영향을 미치지 않는다는 가정
역사로 배우는 양자이론 41편 벨 부등식 1: EPR 세계 (Bell's Inequality)
이번 41편은 벨에 의하여 제안되는 실재성과 국소성을 만족하는 세계에서 항상 성립하는 간단한 식인 벨 부등식을 설명하겠습니다
이 양자이론 시리즈 본편의 4부 양자얽힘은 매주 15-20분 정도의 동영상 1편을 주말에 올리려고 합니다. 필요에 따라 수학적 설명등을 추가한 보조편도 올리려고 합니다.

Bell's theorem
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. "Local" here refers to the principle of locality, the idea that a particle can only be influenced by its immediate surroundings, and that interactions mediated by physical fields cannot propagate faster than the speed of light. "Hidden variables" are putative properties of quantum particles that are not included in quantum theory but nevertheless affect the outcome of experiments. In the words of physicist John Stewart Bell, for whom this family of results is named, "If [a hidden-variable theory] is local it will not agree with quantum mechanics, and if it agrees with quantum mechanics it will not be local."[1]

Bell test
A Bell test, also known as Bell inequality test or Bell experiment, is a real-world physics experiment designed to test the theory of quantum mechanics in relation to Albert Einstein's concept of local realism. Named for John Stewart Bell, the experiments test whether or not the real world satisfies local realism, which requires the presence of some additional local variables (called "hidden" because they are not a feature of quantum theory) to explain the behavior of particles like photons and electrons. As of 2015[update], all Bell tests have found that the hypothesis of local hidden variables is inconsistent with the way that physical systems behave.[1]
