测量仪器的识别与距离测量
Identification and Distance Measures of Measurement Apparatus
摘要：
我们提出了一些简单的方案，可以完美地识别从有限集中秘密选择的投影测量装置。在这些方案中，纠缠的使用，使可能的完美的识别，并显着提高效率。根据辨识结果，对如何合理地确定测量距离的问题进行了讨论。
英文摘要：
We propose simple schemes that can perfectly identify projective measurement apparatus secretly chosen from a finite set. Entanglements are used in these schemes both to make possible the perfect identification and to improve the efficiency significantly. A brief discussion on the problem of how to appropriately define distance measures of measurements is also provided based on the results of identification.
