量子纠缠的部分去神秘化
Quantum entanglement partly demystified
AI总结：
本文提出与弦理论无关的宏观绳线模型，通过多种变体说明 Bell-CHSH 与无信号条件，并结合隐测量解释阐释纠缠关联的语境生成及非空间实在观。
摘要：
我们考虑一个简单的绳线模型，用以解释量子纠缠现象并在一定程度上去除其神秘色彩。该模型与弦理论毫无关系：它使用宏观绳线，Alice 和 Bob 可以以不同方式作用于这些绳线，从而以不同方式违反或不违反 Bell-CHSH 不等式以及无信号条件（也称为边际定律）。我们提出了该模型的若干变体，以回应可能出现的不同反对意见。这使我们能够充分展示量子形式体系已经暗示的内容，即与纠缠态相关的关联的本质——这些关联似乎是在每次执行联合测量时以语境化方式产生的。我们还简要介绍了隐测量解释，其基本原理与我们的绳线模型所暗示的机制相容；随后就以下可能性提出了一些最终思考：量子纠缠现象可能不仅影响状态，还影响测量，而我们的物理实在在本质上将主要是非空间性的。
英文摘要：
We consider a simple string model to explain and partly demystify the phenomenon of quantum entanglement. The model in question has nothing to do with string theory: it uses macroscopic strings that can be acted upon by Alice and Bob in ways that violate, or fail to violate, in different ways Bell-CHSH inequalities and the no-signaling conditions, also called marginal laws. We present several variants of the model, to address different objections that may arise. This allows us to make fully visible what the quantum formalism already suggests, about the nature of the correlations associated with entangled states, which appear to be created in a contextual manner at each execution of a joint measurement. We also briefly present the hidden measurement interpretation, whose rationale is compatible with the mechanism suggested by our string model, then offer some final thoughts about the possibility that the quantum entanglement phenomenon might affect not only states, but also measurements, and that our physical reality would be predominantly non-spatial in nature.
