Methods for, and limitations to, the generation of entangled states of trapped atomic ions are examined. As much as possible, state manipulations are described in terms of quantum logic operations since the conditional dynamics implicit in quantum logic is central to the creation of entanglement. Keeping with current interest, some experimental issues in the proposal for trappedion quantum computation by J. I. Cirac and P. Zoller (University of Innsbruck) are discussed. Several possible decoherence mechanisms are examined and what may be the more important of these are identified. Some potential applications for entangled states of trapped-ions which lie outside the immediate realm of quantum computation are also discussed.
研究了捕获原子离子纠缠态的产生方法及其局限性。尽可能根据量子逻辑操作来描述态操纵，因为量子逻辑中隐含的条件动力学是纠缠产生的核心。紧跟当前的研究热点，讨论了由因斯布鲁克大学的J. I. 西拉克和P. 措勒提出的捕获离子量子计算方案中的一些实验问题。研究了几种可能的退相干机制，并确定了其中可能更重要的机制。还讨论了捕获离子纠缠态在量子计算直接领域之外的一些潜在应用。
