| Outline of Final Research Achievements |
We analyzed the computational power of quantum computers that have restrictions on memory accesses. It was shown that there is a quantum automaton that can recognize a certain language, while the classical counterpart cannot recognize it. This implies that there is a function that can be computed by a quantum automaton, while it cannot be computed by the classical counterpart; quantum computers can be more powerful than classical computers.
Moreover, we developed several methods that boost quantum computer simulators.
