Bell's theorem is refuted by presenting a counterexample that correctly predicts the expectation values of QM. As Bell only ruled out non-contextual models, a contextual model with hidden variables can refute his theorem. Such a model, which is able to explain the spin measurement results with entangled photons or electrons, is presented herein. It is not ruled out by the Kochen-Specker theorem. A physical justification for the contextual behaviour of entangled systems is provided. Consequences for the feasibility of quantum computers are discussed.

反驳贝尔定理的上下文模型

通过提出一个正确预测 QM 期望值的反例来驳斥贝尔定理。由于 Bell 只排除了非上下文模型，因此带有隐藏变量的上下文模型可以反驳他的定理。本文提出了这样一个模型，它能够解释纠缠光子或电子的自旋测量结果。Kochen-Specker 定理不排除它。提供了纠缠系统上下文行为的物理理由。讨论了量子计算机可行性的后果。
