对离子阱退相干的理解

Towards the understanding of Decoherence on Ion Traps

M. O. Terra Cunha, M. C. Nemes

摘要:

研究了离子阱中退相干的两种机制,特别是与实验相关的[Kielpinski等人,Science 291(2001)1013]。对未知变量进行统计假设,并为每个机制计算最佳实验模式的可见性的预期行为。实验数据进行了分析,并显示不足以区分它们。我们建议在现有设施稍作改动的情况下作出改善。

英文摘要:

Two mechanisms of decoherence in ion traps are studied, specially related to the experiment [Kielpinski et al., Science 291 (2001) 1013]. Statistical hypothesis are made about the unknown variables and the expected behaviour of the visibility of the best experimental pattern is calculated for each mechanism. Data from the experiment are analyzed and show to be insufficient to distinguish between them. We suggest improvements which can do this with slight modifications in the present facilities.
