Probabilistic Reversible Automata and Quantum Automata
Marats Golovkins, Maksim Kravtsev · arXiv (Cornell University) · 2002
To study relationship between quantum finite automata and probabilistic finite automata, we introduce a notion of probabilistic reversible automata (PRA, or doubly stochastic automata). We find that there is a strong relationship between different possible models of PRA and corresponding models of quantum finite automata. We also propose a classification of reversible finite 1-way automata.
