摘要
We propose a scheme for deterministically generating three-dimensional (3D) entanglement between two distant five-level atoms based on the dispersive atom-field interaction. In our scheme, the two atoms are trapped separately in two spatially separated optical cavities coupled by an optical fiber. To check the experimental feasibility of our scheme, we numerically simulated effects of the atomic spontaneous decay and photon leakage out of the fiber, and the numerical simulation shows that those effects can be suppressed by appropriately choosing the frequency detuning of atom-field and the coupling intensity of cavity fiber, respectively. We also discussed the influence of photon leakage out of the cavities, and the strictly numerical simulation shows our proposal is good enough to demonstrate the generation of 3D entanglement with high fidelity and within the current experimental technology.
