我们提出了一个基于石墨烯的双量子点系统的实验演示，该系统表现出串联耦合的两个横向量子点的单电子输运。低温传输测量揭示了蜂窝电荷稳定性图与不同的（从弱到强）interdot隧道耦合制度，我们已经提取了相关的参数与双量子点系统。这些结果对于在石墨烯电子学中实现集成量子电路非常重要。
We present an experimental demonstration of a graphene-based double quantum dot system, which exhibits single-electron transport of two lateral quantum dots coupled in series. Low-temperature transport measurements revealed honeycomb charge stability diagrams with a varied (from weak to strong) interdot tunnel-coupling regime, and we have extracted the relevant parameters associated with the double quantum dot system. These results are important for the realization of integrated quantum circuits in graphene-based electronics.
