标题： Measurement uncertainties in the quantum formalism: quasi-realities of individual systems

摘要： 量子测量中的不确定性评估存在问题，因为在状态制备和测量之间可观测量的正确值在实验上无法获得。 在Ozawa关于量子测量的不确定性关系的表述中，可观测量的正确值由该可观测量的算符表示。 在这里，我考虑了这种基于算符对单个系统的赋值的含义，并讨论了它与弱值和弱测量统计的关系。 显示英文摘要

摘要： The evaluation of uncertainties in quantum measurements is problematic since the correct value of an observable between state preparation and measurement is experimentally inaccessible. In Ozawa's formulation of uncertainty relations for quantum measurements, the correct value of an observable is represented by the operator of that observable. Here, I consider the implications of this operator-based assignment of values to individual systems and discuss the relation with weak values and weak measurement statistics.
