Certifying the performance of available quantum computing hardware requires standardized tests. We propose a simple energy estimation benchmark to scrutinize actual output against gate and readout errors reported for the IBM Quantum System One platform, where we collected unprecedented amount of data from several devices, mostly from the one in Ehningen, Germany. We observe oscillations of the benchmark data with a characteristic timescale of two hours, as well as outliers. This suggests that current mitigation techniques need to be adapted to account for nontrivial time dependencies of the devices’ output.

量子计算硬件的能量估计基准

验证可用量子计算硬件的性能需要标准化测试。我们提出了一种简单的能量估计基准，用于根据 IBM Quantum System One 平台报告的门和读出错误来检查实际输出，在该平台上，我们从多个设备（主要来自德国埃宁根的设备）收集了前所未有的数据量。我们观察了特征时间尺度为两小时的基准数据的振荡以及异常值。这表明当前的缓解技术需要进行调整，以解决设备输出的重要时间依赖性。
