This article aims to contribute to the ongoing task of clarifying the relationships between reality, probability, and nonlocality in quantum physics. It is in part stimulated by Khrennikov’s argument, in several communications, for “eliminating the issue of quantum nonlocality” from the analysis of quantum entanglement. I argue, however, that the question may not be that of eliminating but instead that of further illuminating this issue, a task that can be pursued by relating quantum nonlocality to other key features of quantum phenomena. I suggest that the following features of quantum phenomena and quantum mechanics, distinguishing them from classical phenomena and classical physics—(1) the irreducible role of measuring instruments in defining quantum phenomena, (2) discreteness, (3) complementarity, (4) entanglement, (5) quantum nonlocality, and (6) the irreducibly probabilistic nature of quantum predictions—are all interconnected, so that it is difficult to give an unconditional priority to any one of them. To argue this case, I shall consider quantum phenomena and quantum mechanics from a nonrealist or, in terms adopted here, “reality-without-realism” (RWR) perspective. This perspective extends Bohr’s view, grounded in his analysis of the irreducible role of measuring instruments in the constitution of quantum phenomena.

“物体与测量仪器之间不可避免的相互作用”：量子物理学中的现实、概率和非定域性

本文旨在为阐明量子物理学中现实、概率和非定域性之间关系的持续任务做出贡献。它在一定程度上受到赫连尼科夫在数次通讯中的论点的启发，即从量子纠缠的分析中“消除量子非局域性问题”。然而，我认为问题可能不是消除问题，而是进一步阐明这个问题，这是一项可以通过将量子非局域性与量子现象的其他关键特征联系起来来实现的任务。我建议将量子现象和量子力学的以下特征与经典现象和经典物理学区分开来——（1）测量仪器在定义量子现象中的不可约化作用，（2）离散性，（3）互补性，（4）纠缠, (5) 量子非局域性，(6) 量子预测不可约的概率性质——都是相互关联的，因此很难对其中任何一个给予无条件的优先权。为了论证这种情况，我将从非现实主义的角度考虑量子现象和量子力学，或者用这里采用的术语来说，“现实没有现实主义”（RWR）的角度。这种观点扩展了玻尔的观点，其基础是他对测量仪器在量子现象构成中不可简化的作用的分析。
