Query: A Quantum Finite Automata Approach to Modeling the Chemical Reactions   In recent years, the modeling interest has increased significantly from the
molecular level to the atomic and quantum scale. The field of computational
chemistry plays a significant role in designing computational models for the
operation and simulation of systems ranging from atoms and molecules to
industrial-scale processes. It is influenced by a tremendous increase in
computing power and the efficiency of algorithms. The representation of
chemical reactions using classical automata theory in thermodynamic terms had a
great influence on computer science. The study of chemical information
processing with quantum computational models is a natural goal. In this paper,
we have modeled chemical reactions using two-way quantum finite automata, which
are halted in linear time. Additionally, classical pushdown automata can be
designed for such chemical reactions with multiple stacks. It has been proven
that computational versatility can be increased by combining chemical
accept/reject signatures and quantum automata models.
