The quantum anomalous Hall effect holds promise for quantum resistance metrology, but has been limited to low operating currents. A measurement scheme that increases the effect’s operational current is now demonstrated — a scheme that could also be used more generally to improve the performance of existing primary quantum standards of resistance based on the conventional quantum Hall effect.

用于量子电阻计量的电压平衡装置

量子反常霍尔效应为量子电阻计量带来了希望，但仅限于低工作电流。现在展示了一种增加效应工作电流的测量方案，该方案也可以更广泛地用于提高基于传统量子霍尔效应的现有初级量子电阻标准的性能。
