论文摘要
我们以一系列注释报告了我们在阿里巴巴云量子开发平台（AC-QDP）上的工作。 AC-QDP提供了一组工具，用于协助量子计算算法和量子处理器的开发，并由部署在阿里巴巴云上的大规模经典模拟器提供动力。在本说明中，我们使用实验噪声参数在平面电路QED架构中使用实验噪声参数模拟距离3的逻辑量子量子。我们的仿真特征是由ZZ Interactions引起的串扰。我们表明，在当前噪声水平上，串扰对逻辑量子的影响显着贡献。这会导致总相折叠概率为$ \ sim 0.6 \％$，而无需考虑串扰的情况下，$ 60 \％$高。这表明，对于考虑的代码，当前的噪声参数接近但尚未达到的，即断裂耐受耐受性态度。
We report, in a sequence of notes, our work on the Alibaba Cloud Quantum Development Platform (AC-QDP). AC-QDP provides a set of tools for aiding the development of both quantum computing algorithms and quantum processors, and is powered by a large-scale classical simulator deployed on Alibaba Cloud. In this note, we simulate a distance-3 logical qubit encoded in the 17-qubit surface code using experimental noise parameters for transmon qubits in a planar circuit QED architecture. Our simulation features crosstalk induced by ZZ-interactions. We show that at the current-stage noise levels, crosstalk contributes significantly to the dephasing of the logical qubit. This results in a total phase-flip probability of $\sim 0.6\%$, about $60\%$ higher than expected without considering crosstalk. This indicates that for the code considered, the current noise parameters approach, but do not yet meet, the break-even fault-tolerance regime.
