“局部实在论”、Bell定理和量子“局部实在”不等式

"Local Realism", Bell's Theorem and Quantum "Locally Realistic" Inequalities

Elena R. Loubenets

摘要:

基于新的一般框架的概率描述的实验,介绍了在quant-ph/0305126,quant-ph/0312199,我们分析了在数学方面的有效性贝尔型不等式联合实验后,任何类型的系统和物理概念的“本地现实主义”之间的联系。我们证明了量子情形下Bell型不等式的破坏与“局域实在论”的破坏无关。在一般情况下,我们制定了数学术语的条件下,“局部现实主义”的联合实验,并考虑量子“局部现实主义”的联合实验的例子。我们,特别是,表明量子联合实验的爱丽丝/鲍勃类型是“本地现实”。对于任意的二分量子态,我们导出了原来的贝尔不等式的量子类似。根据我们的结果,我们认为,贝尔型不等式在量子情况下的破坏不能是一个有效的参数在讨论局域性或非局域性的量子相互作用。

英文摘要:

Based on the new general framework for the probabilistic description of experiments, introduced in quant-ph/0305126, quant-ph/0312199, we analyze in mathematical terms the link between the validity of Bell-type inequalities under joint experiments upon a system of any type and the physical concept of "local realism". We prove that the violation of Bell-type inequalities in the quantum case has no connection with the violation of "local realism". In a general setting, we formulate in mathematical terms a condition on "local realism" under a joint experiment and consider examples of quantum "locally realistic" joint experiments. We, in particular, show that quantum joint experiments of the Alice/Bob type are "locally realistic". For an arbitrary bipartite quantum state, we derive quantum analogs of the original Bell inequality. In view of our results, we argue that the violation of Bell-type inequalities in the quantum case cannot be a valid argument in the discussion on locality or non-locality of quantum interactions.
