表征NISQ器械的稳定性
Characterizing the Stability of NISQ Devices
摘要：
在这项研究中，我们专注于NISQ设备的稳定性问题。定义器件稳定性曲线的参数是由Dijuenzo的工作激发的，Dijuenzo讨论了量子计算的物理实现要求。我们开发的指标和理论框架，以量化的Diplenenzo的要求，并研究这些关键指标的稳定性。我们评估的基础是直方图相似性（在时间和空间上）。对于相同的实验，在时间上产生可再现的直方图并且在空间上产生相似的直方图的设备被认为是更可靠的。为了研究这种可靠性问题鲁棒，我们提出了一个基于矩的距离（MBD）度量。我们说明了我们的方法，从IBM的约克镇设备收集的数据。两种类型的评估进行了讨论：空间稳定性和时间稳定性。
英文摘要：
In this study, we focus on the question of stability of NISQ devices. The parameters that define the device stability profile are motivated by the work of DiVincenzo where the requirements for physical implementation of quantum computing are discussed. We develop the metrics and theoretical framework to quantify the DiVincenzo requirements and study the stability of those key metrics. The basis of our assessment is histogram similarity (in time and space). For identical experiments, devices which produce reproducible histograms in time, and similar histograms in space, are considered more reliable. To investigate such reliability concerns robustly, we propose a moment-based distance (MBD) metric. We illustrate our methodology using data collected from IBM's Yorktown device. Two types of assessments are discussed: spatial stability and temporal stability.
