唯测量子自动机识别语言类的代数特征

Algebraic Characterization of the Class of Languages recognized by Measure Only Quantum Automata

Carlo Comin, Maria Paola Bianchi

摘要:

我们研究了一个只允许测量操作的单向量子自动机模型(MOn-1 qfa)。给出了LMO的一个代数刻画,证明了LMO语言的句法幺半群是J-平凡字面幂等幺半群的字面伪簇,其中J是由双边理想确定的Green关系.我们还证明了LMO与字面幂等分段可测试正则语言的字面簇一致。这使我们能够证明存在一个多项式时间算法来决定一个正则语言是否属于LMO。

英文摘要:

We study a model of one-way quantum automaton where only measurement operations are allowed (MOn-1qfa). We give an algebraic characterization of LMO, showing that the syntactic monoids of the languages in LMO are exactly the literal pseudovariety of J-trivial literally idempotent monoids, where J is the Green's relation determined by two-sided ideals. We also prove that LMO coincides with the literal variety of literally idempotent piecewise testable regular languages. This allows us to prove the existence of a polynomial time algorithm for deciding whether a regular language belongs to LMO.
