我们研究了平行耦合的横向双量子点的电子态。根据两个点的栅极电压，给出了电荷稳定性图。我们发现，随着点间耦合强度的增加，两个电子态不断地从分离态向耦合态转变。我们的结果表明，平行量子点的可调性预示着未来量子计算的应用前景。
We study the electron states on lateral double quantum dots coupled in parallel. The charge stability diagrams are given in terms of the gate voltages of both dots. We discover that the two electron states translate from separated states to coupled states continuously by increasing the inter-dot coupling strength. Our results demonstrate that the parallel-quantum-dot tunability bodes well for future quantum computing applications.
