量子测量中可观测量的上下文值

Contextual Values of Observables in Quantum Measurements

J. Dressel, S. Agarwal, A. N. Jordan

摘要:

我们引入上下文值作为一个观察到的特征值,考虑到系统的观察和一般的测量过程的概括。这种技术导致一个自然的定义,一般的条件平均,唯一收敛到量子弱值的最小扰动极限。因此,我们解决了文献中关于量子弱值的理论一致性的争议,提供了一个更一般的理论框架,并给出了几个例子,说明该框架如何与现有的实验和理论结果。

英文摘要:

We introduce contextual values as a generalization of the eigenvalues of an observable that takes into account both the system observable and a general measurement procedure. This technique leads to a natural definition of a general conditioned average that converges uniquely to the quantum weak value in the minimal disturbance limit. As such, we address the controversy in the literature regarding the theoretical consistency of the quantum weak value by providing a more general theoretical framework and giving several examples of how that framework relates to existing experimental and theoretical results.
