量子有限单计数器自动机

Quantum Finite One-Counter Automata

Maksim Kravtsev

摘要:

本文引入了量子有限单计数器自动机(QF1CA)的概念。这一概念的引入类似于A.Kondacs和J.Watrous提出的双向量子有限态自动机。指定的自动机的良构性条件,以确保统一的进化。引入一种特殊的QF1CA,称为简单的,满足良构性条件。这允许指定规则来构造这样的自动机,比一般情况下更自然,更简单。被认为是可能的模式的语言识别QF1CA。一些语言的识别QF1CA示出和识别的概率同行相比。

英文摘要:

In this paper the notion of quantum finite one-counter automata (QF1CA) is introduced. Introduction of the notion is similar to that of the 2-way quantum finite state automata by A.Kondacs and J.Watrous. The well-formedness conditions for the automata are specified ensuring unitarity of evolution. A special kind of QF1CA, called simple, that satisfies the well-formedness conditions is introduced. That allows to specify rules for constructing such automata more naturally and simpler than in general case. Possible models of language recognition by QF1CA are considered. The recognition of some languages by QF1CA is shown and compared with recognition by probabilistic counterparts.
