Data for the publication Fast microwave-driven two-qubit gates between fluxonium qubits with a transmon coupler.

Experimental and numerical dataset concerning the work titled as - "Fast microwave-driven two-qubit gates between fluxonium qubits with a transmon coupler". The dataset includes the measurement data taken on the device for the characterization of the qubits. The measurement includes different calibrations for the gates and finally running the RB results to measure the fidelities. We perform the RB with three different kinds of pulse shapes at varying gate durations, to acquire a comparative result of the performance of the gate. The experimental dataset was acquired during two different cooldowns and thus the folders are named based on the cooldown. Additionally we use numerical simulations to account for system uncertainties in the experiment and use the simulated results for comparison. The results for this simulation are included in the data.zip. A detailed description of the file types and contents in the dataset is described in the readme file.

本数据集为题为《使用传输量子比特耦合器（transmon coupler）实现磁通量子比特（fluxonium qubits）间的快速微波驱动双量子比特门》（Fast microwave-driven two-qubit gates between fluxonium qubits with a transmon coupler）的研究工作配套的实验与数值混合数据集。数据集包含针对该量子比特表征器件的实测数据，实测内容涵盖各类量子门校准流程，最终通过随机基准测试（Random Benchmarking，RB）获取量子门保真度。我们采用三种不同脉冲波形，并在可变门控时长下开展随机基准测试，以对比该双量子比特门的性能表现。本实验数据集采集自两次独立的制冷循环（cooldown），因此数据集文件夹以对应制冷循环命名。此外，为量化实验中的系统不确定性，我们开展了数值仿真并将仿真结果用于与实验结果的对比分析，相关仿真结果已收录于data.zip压缩包中。数据集内的文件类型与具体内容的详细说明，请参阅readme文件。
