Summarily, the introduced work lays a foundation for further studies on more complicated quantum automata and quantum grammars such as quantum pushdown automata and Turing machine as well as quantum context-free grammars and context-sensitive grammars.

• 因此；为进一步研究更复杂的量子自动机(如量子下推自动机和Turing机)和量子文法(如量子上下文无关文法和上下文有关文法)奠定了基础.
