Data and code underlying the publication: Operating semiconductor quantum processors with hopping spins

This repository contains datasets, analysis codes and simulations used in the manuscript "Operating semiconductor quantum processors with hopping spins" by Wang et al. as first submitted in February 2024. This manuscript is about experimental results of spin-qubit in gate-defined germanium quantum dots. The data is collected by thresholding the averaged voltage signals amplified by CITLF3 cryogenic amplifiers and in-house built LNA (M2j), down-converted by in-house built IQ-mixer (F1d) and measured by the digitizers Keysight M3102A at specific timing defined by the arbitrary waveform generators Keysight M3202A which output specific voltage waveforms to the devices under test. More details regarding research objective and method of data collection are described in the manuscript which will be public soon. The type of dataset are in the formats of .hdf5, .dat, .pickle, and .json. They can be opened to replot the figures by the provided python scripts in the python environment with several packages installed. More details about the required python packages are in the README files.本仓库包含Wang等人于2024年2月首次提交的手稿《利用自旋跳跃操控半导体量子处理器》（Operating semiconductor quantum processors with hopping spins）中使用的数据集、分析代码与仿真程序。本手稿聚焦于栅极定义锗量子点中自旋量子比特的实验研究成果。本数据集的采集流程如下：对经CITLF3低温放大器及自研低噪声放大器（Low Noise Amplifier，M2j）放大后的平均电压信号进行阈值处理，再通过自研正交混频器（IQ-mixer，F1d）完成下变频，随后由Keysight M3102A型数字化仪在指定时序下完成测量；该指定时序由向被测器件输出特定电压波形的Keysight M3202A型任意波形发生器定义。有关本研究的研究目标与数据采集方法的更多细节，将在即将公开的手稿中详述。本数据集包含.hdf5、.dat、.pickle及.json四种格式的文件。用户可在安装了相关依赖包的Python环境中，通过本仓库提供的Python脚本读取上述数据并复现手稿中的图表。有关所需Python依赖包的详细信息，请参阅仓库中的README文件。
