论文摘要
给定量子系统的本体论模型，与量子测量相反，“真正的测量”是指确定beable值的实验，即根据模型，该实验在实验前具有实际价值。我们证明了一个定理表明，在每个本体论模型中，都无法衡量所有素质。换句话说，没有实验可以可靠地决定这种状态。该结果表明，物理理论应仅涉及可观察数量的实证主义观念过于乐观。
Given an ontological model of a quantum system, a "genuine measurement," as opposed to a quantum measurement, means an experiment that determines the value of a beable, i.e., of a variable that, according to the model, has an actual value in nature before the experiment. We prove a theorem showing that in every ontological model, it is impossible to measure all beables. Put differently, there is no experiment that would reliably determine the ontic state. This result shows that the positivistic idea that a physical theory should only involve observable quantities is too optimistic.
