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.
