超冷里德堡原子的Blockade效应对构建量子逻辑门以及量子信息存储的研究有重要意义。本文介绍了这方面的研究进展,主要包括：超冷里德堡原子之间长程Van de Waals相互作用和偶极-偶极相互作用的机理,由相互作用产生的Blockade效应,并阐述了利用单里德堡原子激发构建量子逻辑门的可能性。

The dipole blockade of ultracold Rydberg atoms plays a significant role in the formation of quantum logic gate and the investigation of quantum information storage.The interaction between ultracold Rydberg atoms is presented,furthermore the mechanisms of long range Van de Waals interactions and dipole-dipole interactions as well as excitation blockade of ultracold Rydberg atoms are presented.The possibility of constructing quantum logic gate based on single Rydberg atom excitation is described.
