    摘要:The preparation process of quantum Bell states is investigated using two -type Rydberg atoms for the carriers. Two ground states and of the -type atoms are defined as logical states and to establish the physical model for preparing quantum state based on the quantum Zeno dynamics theory. Further, the theoretical analysis and derivation for the physical model are completed, and preparation of Bell state is obtained. Finally, feasibility analysis about the preparation scheme of Bell states is made. The transitions between atomic energy levels can be avoided after completing preparation of Bell state because the logic states and are all the ground states in this work.
