论文摘要
贝尔非本地性是一个适用于量子力学的特定修改和解释的术语。然而,贝尔的1964年定理经常被用来断言未经修改的量子力学本身是非本地的,而当地的现实主义解释是站不住脚的。在贝尔的原始不等式的推动下,我们确定了四种可行的量子理论类别:局部量子力学,超确定性,非本地倒塌量子力学和非本地隐藏变量理论。但是,这些类别并不受Bell对当地的定义的限制。鉴于当前可用的无关定理,本地和确定性的描述似乎已经忽略了,这可能是贝尔本地性和更广泛的当地原则之间的混合原因。我们介绍了可以局部量子信息流动的理论的例子,并评估当前的实验建议和改进的科学哲学是否可以对比解释并区分它们。
Bell non-locality is a term that applies to specific modifications and interpretations of quantum mechanics. Yet, Bell's original 1964 theorem is often used to assert that unmodified quantum mechanics itself is non-local and that local realist interpretations are untenable. Motivated by Bell's original inequality, we identify four viable categories of quantum theories: local quantum mechanics, superdeterminism, non-local collapse quantum mechanics, and non-local hidden variable theories. These categories, however, are not restricted by Bell's definition of locality. In light of currently available no-go theorems, local and deterministic descriptions seem to have been overlooked, and one possible reason for that could be the conflation between Bell-locality and a broader principle of locality. We present examples of theories where a local flow of quantum information is possible, and assess whether current experimental proposals and an improved philosophy of science can contrast interpretations and distinguish between them.
