利用绝热技术提出制备W态和两原子高维纠缠态方案．在这些方案中，量子信息都存储在原子的基态上，且系统仅在暗态空间中演化，原子在激发态上无布居，这使得原子的自发辐射效应大大受到抑制．另外，绝热技术确保这些方案对实验参数的涨落具有强的鲁棒性．其方法操作步骤简单，既有效节省了资源，同时更容易在实验上实现．

Schemes are presented for preparation for W state and high-dimensional entangled states of two atoms via adiabatic passage. In these schemes,since the quantum information is encoded in atomic ground states and the system always evolves in the dark state space so that there is no population in the atomic excited state, the atomic spontaneous emission is suppressed effectively. In addition, adiabatic passage insures that these schemes are robust to the fluctuation of the experimental parameter. Compared with previous proposals, our project saves effectively resources and can be experimentally realized more easily due to simpler operation.
