我们提出了一种通过光学偶极力引起的线性保罗陷阱中离子的内部状态相关位移来实现量子逻辑门的方法。基于系统动力学的一般量子分析，我们考虑碱土金属离子的具体实现。对于实验上真实的参数，可以获得低至 10{sup -4} 的门控不忠度。
We propose an implementation of quantum logic gates via internal state dependent displacements of ions in a linear Paul trap caused by optical dipole forces. Based on a general quantum analysis of the system dynamics we consider specific implementations with alkaline-earth-metal ions. For experimentally realistic parameters gate infidelities as low as 10{sup -4} can be obtained.
