Abstract
A novel private database query protocol with only one quantum state is proposed. The database owner Bob sends only one quantum state to the user Alice. The proposed protocol combines the idea of semiquantum key distribution and private query. It can be implemented in the situation where not all the parties can afford expensive quantum resources and operations. So our proposal is more practical in use. We also prove that the proposed protocol is secure in terms of the user security and the database security.
