We introduce an open-source software package for error mitigation in quantum computation using zero-noise extrapolation. Error mitigation techniques improve computational performance (with respect to noise) with minimal overhead in quantum resources by relying on a mixture of quantum sampling and classical post-processing techniques. Our error mitigation package interfaces with multiple quantum computing software stacks, and we demonstrate improved performance on IBM and Rigetti superconducting quantum processors as well as noisy simulators. We describe the library using code snippets to demonstrate usage and discuss features and contribution guidelines.

Mitiq：用于在嘈杂的量子计算机上缓解错误的软件包

我们引入了一个开源软件包，用于使用零噪声外推的量子计算中的错误缓解。错误缓解技术依靠量子采样和经典后处理技术的混合，以最小的量子资源开销提高计算性能（相对于噪声）。我们的错误缓解包与多个量子计算软件堆栈接口，我们在 IBM 和 Rigetti 超导量子处理器以及嘈杂的模拟器上展示了改进的性能。我们使用代码片段来描述库以演示用法并讨论功能和贡献指南。
