摘要:

我们提出了同时操作的10个单电子旋转门导致一个数量级的电流水平增加到100 pA。我们对器件均匀性和背景电荷稳定性的分析表明,并行化可以在不影响量子精密测量对精度和电流水平的严格要求的情况下进行。此外,我们还讨论了偏置电荷不稳定性如何限制单电子旋转门的集成规模。

英文摘要:

We present simultaneous operation of ten single-electron turnstiles leading to one order of magnitude increase in current level up to 100 pA. Our analysis of device uniformity and background charge stability implies that the parallelization can be made without compromising the strict requirements of accuracy and current level set by quantum metrology. In addition, we discuss how offset charge instability limits the integration scale of single-electron turnstiles.
