量子态滤波与布尔函数集之间的鉴别
Quantum state filtering and discrimination between sets of Boolean functions
摘要:
量子态过滤的问题包括确定从一组已知态中选择的未知量子态是否是特定的、指定的态。我们认为这个问题的情况下,过滤过程是明确的,这就需要承认不确定的答案时,给定的状态是不正交的。作为一个应用程序,我们提出了一个有效的,概率的程序区分布尔函数集,这是一个扩展的Deutsch-Jozsa算法。
英文摘要:
The problem of quantum state filtering consists of determining whether an unknown quantum state, which is chosen from a known set of states, is either a particular, specified state, or not. We consider this problem for the case that the filtering procedure is required to be unambiguous, which necessitates admitting inconclusive answers when the given states are not orthogonal. As an application, we propose an efficient, probabilistic procedure for distinguishing between sets of Boolean functions, which is an extension of the Deutsch-Jozsa algorithm.
