利用三个振荡场连接的单Ca-40（+）离子四能级系统，证明了绝热过程中基于纯几何相位因子的普适单量子比特操作.对参数变化的鲁棒性进行了研究。这里演示的方案可以用作大规模完整量子计算的构建块，这可能是有用的大量子比特系统与系统参数的统计变化。
Universal single-qubit operations based on purely geometric phase factors in adiabatic processes are demonstrated by utilizing a four-level system in a trapped single Ca-40(+) ion connected by three oscillating fields. Robustness against parameter variations is studied. The scheme demonstrated here can be employed as a building block for large-scale holonomic quantum computations, which may be useful for large qubit systems with statistical variations in system parameters.
