Contribution
It introduces new theoretical insights into the recognition power of quantum finite automata with unbounded error, extending previous models.
Findings
Quantum finite automata recognize certain non-regular languages
Unbounded error models have greater recognition power than bounded error models
The paper establishes hierarchy results for quantum automata classes
