摘要:

离子阱提供了研究基本量子系统的机会,具有高精度,与环境高度解耦。单个原子离子可以用电场控制和操纵,用激光冷却冷却到运动的基态,并使用光学和微波辐射进行相干操纵。微制造的离子阱具有允许更小的阱尺寸和更好的可扩展性的优点,这也使它们成为下一代量子技术的重要组成部分。在这里,我们提供了一个微型离子阱的原理和操作的介绍。我们展示了材料和电气方面的考虑,这是至关重要的设计这样的陷阱结构的概述。我们提供指导,在如何选择适当的制造设计,考虑不同的方法,制造的微离子阱和讨论以前实现的结构。我们还讨论了离子阱中离子的反常加热现象,这是离子阱小型化的一个重要因素。

英文摘要:

Ion traps offer the opportunity to study fundamental quantum systems with high level of accuracy highly decoupled from the environment. Individual atomic ions can be controlled and manipulated with electric fields, cooled to the ground state of motion with laser cooling and coherently manipulated using optical and microwave radiation. Microfabricated ion traps hold the advantage of allowing for smaller trap dimensions and better scalability towards large ion trap arrays also making them a vital ingredient for next generation quantum technologies. Here we provide an introduction into the principles and operation of microfabricated ion traps. We show an overview of material and electrical considerations which are vital for the design of such trap structures. We provide guidance in how to choose the appropriate fabrication design, consider different methods for the fabrication of microfabricated ion traps and discuss previously realized structures. We also discuss the phenomenon of anomalous heating of ions within ion traps, which becomes an important factor in the miniaturization of ion traps.
