The scope of the work was to characterize exchange cross-talk in dense quantum dot arrays by tracking the avoided crossing position in a 2x4 array of quantum dots in a Ge/SiGe heterostructure. For each experiment, we record the reflected signal of an RF tank circuit which provides information about the charge configuration in the quantum dot array. Datasets involving spin dynamics contain single shot measurements in the Pauli Spin Blockade region. Each datapoint is recorded between 200 and 500 times, thresholded and then plotted as a function of other scan parameters like gate voltage or evolution time.

本研究旨在通过追踪Ge/SiGe异质结构中2×4量子点阵列的免交叉（avoided crossing）位置，表征密集量子点阵列中的交换串扰（exchange cross-talk）。每一项实验中，我们均记录射频槽路电路（RF tank circuit）的反射信号，该信号可提供量子点阵列的电荷组态信息。涉及自旋动力学（spin dynamics）的数据集包含泡利自旋阻塞（Pauli Spin Blockade）区域内的单次测量结果。每个数据点均进行200至500次重复采集，经阈值化处理后，以栅极电压、演化时间等其他扫描参数为函数进行绘图。
