论文摘要
被困的离子是量子计算技术的主要候选者之一。在单独的陷阱中接口离子量子位和与超导码位的离子量子置量位是扩展量子计算机的众多挑战中的两个。克服这两个问题的一种方法是使用导电线来介导不同陷阱或离子和超导码头之间的离子之间的库仑相互作用。为此，长期以来，将被困的带电颗粒诱导电荷诱导的电荷已被建模为等效总元件电子组件的系统。仔细的考虑揭示了该模型推导的两个假设，这些假设在许多感兴趣的情况下是不合理的。我们确定这些假设并解释它们的含义。此外，我们引入了一种使用线性关系来描述被困离子与附近导体的相互作用的改进方法。新方法基于现实的假设，并从非基于电路元素模型的其他作品中复制结果。它针对故障射击实验设计，并允许实验测试和比较不同理论模型的准确性。
Trapped ions are among the leading candidates for quantum computing technologies. Interfacing ion qubits in separate traps and interfacing ion qubits with superconducting qubits are two of the many challenges to scale up quantum computers. One approach to overcome both problems is to use a conducting wire to mediate the Coulomb interaction between ions in different traps, or between ions and superconducting qubits. To this end, a trapped charged particle inducing charge on a conductor has long been modeled as a system of equivalent lumped element electronic components. Careful consideration reveals two assumptions in the derivation of this model which are unjustified in many situations of interest. We identify these assumptions and explain their implications. In addition, we introduce an improved way to use linear relationships to describe the interaction of trapped ions with nearby conductors. The new method is based on realistic assumptions and reproduces results from other works that are not based on the circuit element model. It is targeted for trouble-shooting experimental designs and allows experiments to test and compare the accuracy of different theoretical models.
