Quantum Pushdown Automata with a Garbage Space
Masaki Nakanishi (Yamagata Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Several kinds of quantum pushdown automata have been proposed, and their computational power is investigated
intensively. However, for some quantum pushdown automaton models, it is not known whether quantum models are at least as
powerful as classical counterparts or not. This is due to the reversibility restriction. In this paper, we introduce a new quantum
pushdown automaton model that has a garbage space. This model can overcome the reversibility restriction by exploiting the
garbage space for storing popped symbols. We show that the proposed model can simulate any quantum pushdown automaton
with a classical stack as well as any classical pushdown automaton. We also show that our model can solve a promise problem
with no error while classical deterministic pushdown automata cannot. These results implies that our model is strictly more
powerful than classical counterparts in the setting of exact, one-sided error and non-deterministic computation.
