Abstract: In order to suppress the influence of the environment on quantum teleportation, a scheme of quantum teleportation was presented based on decoherent-free subspace. In this scheme, a kind of disentanglement-free atomic six-bit state is taken as quantum entanglement channel, and the teleportated one logical qubit quantum information is encoded into three-bit atomic state which can avoid against influence of the environment. The properties of the quantum teleportation scheme and its experimental realization were analyzed. The result shows that the whole teleportation process is immune to amplitude-flip and phase-flip noises induced by the environment and the success probability for this scheme is 44%.
