实验精度的概念与位置和动量的同时测量

The Concept of Experimental Accuracy and Simultaneous Measurements of Position and Momentum

D. M. Appleby

摘要:

实验精度的概念进行了研究的背景下,由Arthurs和凯利定义的无偏联合测量过程。追溯误差和预测误差是有区别的。四个误差-干扰关系推导出,类似于单一的误差-干扰关系的背景下,由Braginsky和哈利利的位置只测量。追溯和预测误差误差的关系也来自。讨论了这些关系与Arthurs和Kelly的扩展的不确定原理之间的联系。量子力学和经典概念的实验精度之间的异同进行了探讨。有人认为,这些关系提供的理由质疑Uffink的结论,即同时测量的非交换可观的概念是没有成果的。

英文摘要:

The concept of experimental accuracy is investigated in the context of the unbiased joint measurement processes defined by Arthurs and Kelly. A distinction is made between the errors of retrodiction and prediction. Four error-disturbance relationships are derived, analogous to the single error-disturbance relationship derived by Braginsky and Khalili in the context of single measurements of position only. A retrodictive and a predictive error-error relationship are also derived. The connection between these relationships and the extended Uncertainty Principle of Arthurs and Kelly is discussed. The similarities and differences between the quantum mechanical and classical concepts of experimental accuracy are explored. It is argued that these relationships provide grounds for questioning Uffink's conclusion, that the concept of a simultaneous measurement of non-commuting observables is not fruitful.
