我们证明了通过电容耦合产生电荷-量子比特团簇态是各向异性的。具体地，水平与垂直最近邻量子位间耦合在矩形晶格中不同。我们展示了如何通过对双点阵列施加潜在偏差来改善这种各向异性。
We demonstrate that charge-qubit cluster state generation by capacitive coupling is anisotropic. Specifically, horizontal vs vertical nearest-neighbor inter-qubit coupling differs in a rectangular lattice. We show how to ameliorate this anisotropy by applying potential biases to the array of double dots.
