论文摘要
量子物理学的主要问题之一是将经典的根平方误差推广到量子测量中，以获得满足声音的误差量度（以消失任何准确的测量值）和完整性（仅对于准确的测量而消失）。基于噪声操作机的误差度量已被用于此目的，但事实证明不完整。最近，Ozawa提出了一个新的定义，该定义是基于噪声操作的误差措施既声音又完整。在这里，我们提出了一个中子光学演示，以供投影（或尖锐）以及广义（或UNSHARP）测量的新误差度量的完整性。
One of the major problems in quantum physics has been to generalize the classical root-mean-square error to quantum measurements to obtain an error measure satisfying both soundness (to vanish for any accurate measurements) and completeness (to vanish only for accurate measurements). A noise-operator based error measure has been commonly used for this purpose, but it has turned out incomplete. Recently, Ozawa proposed a new definition for a noise-operator based error measure to be both sound and complete. Here, we present a neutron optical demonstration for the completeness of the new error measure for both projective (or sharp) as well as generalized (or unsharp) measurements.
