论文摘要
可以使用有限特征值光谱可观察到的任何可观察到的谱仪来测量适当的单位转换和一系列检测器仪器，其中每个检测器可作为可观察到的一个可能值的指标。在冯·诺伊曼（Von Neumann）的量子机械测量过程的框架内对该设置的研究具有显着的结果：在测量系统与检测器阵列相互作用之后，已经没有塌陷，恰好一个检测器指示检测。每个单个检测器指示0或1检测，并且不能叠加归因于此。
Any observable with finite eigenvalue spectrum can be measured using a multiport apparatus realizing an appropriate unitary transformation and an array of detector instruments, where each detector operates as an indicator of one possible value of the observable. The study of this setup in the frame of von Neumann's quantum mechanical measurement process has a remarkable result: already after the interaction of the measured system with the detector array without collapse, exactly one detector is indicating a detection. Each single detector indicates either 0 or 1 detection, and no superposition can be attributed to it.
