摘　　要：利用∧型三能级原子与双模腔的相互作用实现量子态的转移.提出了量子信息存储在∧型原子的两个基态,泄漏光子充当飞行比特,有效地抑制了原子自发辐射和环境对系统的消相干效应.为实验上实现量子态转移提供理论基础.A scheme for transfer of atomic states via the interaction of ∧-type three-level atom with the two-mode cavity is proposed. In the proposal,we use the two ground states of the ∧-type three-level atom as memory and the leaky photon acting as flying qubit, which reduces the atomic spontaneous radiation and the decoherence engended by the interaction of the system and the environments. The results provide some theoretical bases for the realization of transfrring atomic states experimentally.
