论文摘要
我们报告了IBM量子计算机中$ U_3 $门的实现时系统错误的观察和表征。该误差似乎是栅极角度之一的一致偏移，其大小与使用Clifford随机基准测试计算得出的IBM引用的错误无关。我们提出了一个简单的缓解程序，从而改善了CHSH不平等的观察值，从而突出了简单缓解策略对短深度量子电路的实用性。
We report the observation and characterisation of a systematic error in the implementation of $U_3$ gates in the IBM quantum computers. The error appears as a consistent shift in one of the angles of the gate, whose magnitude does not correlate with IBM's cited errors calculated using Clifford randomized benchmarking. We propose a simple mitigation procedure, leading to an improvement in the observed value for the CHSH inequality, highlighting the utility of simple mitigation strategies for short-depth quantum circuits.
