Abstract

Inspired by a recent proposal [Z.Q. Yin, F.L. Li, Phys. Rev. A 75, 012324 (2007)], we propose a more efficient and reliable scheme for transferring high fidelity three-dimensional quantum states in a cavity-fiber-cavity system. By employing atomic ensembles in a cavity and large-detuning interaction between atoms and photons, the interaction time can be shortened greatly and the atomic spontaneous emission can be ignored. Furthermore, we study the effects of photon leakage caused by cavity and fiber.
