超越不可分和语境相对论的关系量子纠缠
Relational Quantum Entanglement Beyond Non-Separable and Contextual Relativism
摘要：
在本文中，我们解决的相对论的角度来看，传统的定义量子纠缠的性质的首选因式分解。我们还考虑了Barnum等人提出的广义纠缠定义中的这一方面。[6，7]在首选观测量方面。更具体地说，我们将讨论不可分离的相对主义所隐含的正统定义的纠缠，它的推广所隐含的上下文相对主义，以及目前在专业文献中讨论的其他一些严重的问题。在这项工作的第二部分，我们解决了最近提出的纠缠的客观不变定义，将其理解为有效和密集关系的实际和潜在编码[32]。通过两个定理的推导，我们将清楚地表明，这种新的纠缠的客观定义是如何能够逃脱不可分离的相对主义和上下文相对主义。根据这些定理，在这个建议的关系定义中，所有可能的可观测子集以及所有可能的因子分解都可以全局地被认为是引用相同的（潜在的）事态。结论是，与传统的定义不同，这种新的纠缠的客观关系概念能够从一开始就绕过相对主义，为量子关联的现实主义理解打开大门。
英文摘要：
In this paper we address the relativist-perspectival nature of the orthodox definition of quantum entanglement in terms of preferred factorizations. We also consider this aspect aspect within the generalized definition of entanglement proposed by Barnum et al. [6, 7] in terms of preferred observables. More specifically, we will discuss the non-separable relativism implied by the orthodox definition of entanglement, the contextual relativism implied by its generalization as well as some other serious problems presently discussed within the specialized literature. In the second part of this work, we address a recently proposed objective-invariant definition of entanglement understood as the actual and potential coding of effective and intensive relations [32]. Through the derivation of two theorems we will show explicitly how this new objective definition of entanglement is able to escape both non-separable relativism and contextual relativism. According to these theorems, within this proposed relational definition, all possible subsets of observables as well as all possible factorizations can be globally considered as making reference to the same (potential) state of affairs. The conclusion is that, unlike with the orthodox definitions, this new objective-relational notion of entanglement is able to bypass relativism right from the start opening the door to a realist understanding of quantum correlations.
