在过去的几年里，量子计算（QC）由于量子加速、解决 NPhard 问题的可能性以及实现更高计算能力而引起了计算机科学家的兴趣。然而，减轻每个量子器件内部噪声的影响是一个迫在眉睫的挑战。这些变化为研究校准参数在一定时间内对每个量子位的个体特征的影响提供了新的机会。在本文中，我们基于校准数据和单个设备的特性研究了噪声中级量子（NISQ）计算机的时间行为。特别是，我们收集了过去两年 IBM-Q 机器的校准数据，并将量子误差鲁棒性与 IBM-Q 机器的处理器类型、量子拓扑和量子体积进行了比较。
Over the last couple of years, Quantum Computing (QC) has captured the interest of computer scientists due to the fact of quantum speedup, the possibility of solving NPhard problems, and achieving higher compute power. However, mitigating the impact of the noise inside each quantum device presents an immediate challenge. These changes open up new opportunities to investigate the effect of calibration parameters for individual characteristics of each qubit in a manner of time. In this paper, we investigate the temporal behavior of noisy intermediate-scale quantum (NISQ) computers based on calibration data and the characteristics of individual devices. In particular, we collect calibration data of IBM-Q machines over the last two years and compare the quantum error robustness against the processor types, quantum topology, and quantum volumes of the IBM-Q machines.
