WebIn the past decades, many experiments have been designed to test the Bell’s inequality or Clauser-Horne-Shimony-Holt inequality [1,6{8,10]. Today, the two inequalities are of great impor-tance to quantum information and computation [3,4,11,12]. Very recently, we [5] have shown the math contradictions in Bell’s argument for his inequality.

We investigate for which Bell polytopes the CHSH inequality is also the unique (non-trivial) facet. We prove that the CHSH inequality is the unique facet for all bipartite polytopes where at least one party has a binary choice of dichotomic ... WebNov 10, 2024 · the original Bell inequality requires that outcomes from the same setting are always perfectly anti-correlated. It says nothing about the case where they are even marginally different. by contrast, in CHSH, the ideal (giving maximum violation) is that outcomes from the same setting would be anti-correlated, but it is not required. iron hulled ships
