Noisy Intermediate-Scale Quantum (NISQ) hardware has unavoidable noises, and
crosstalk error is a significant error source. When multiple quantum operations
are executed simultaneously, the quantum state can be corrupted due to the
crosstalk between gates during simultaneous operations, decreasing the circuit
fidelity. In this work, we first report on several protocols for characterizing
crosstalk. Then, we discuss different crosstalk mitigation methods from the
hardware and software perspectives. Finally, we perform crosstalk injection
experiments on the IBM quantum device and demonstrate the fidelity improvement
with the crosstalk mitigation method.

分析 NISQ 时代的串扰误差
噪声中级量子 (NISQ) 硬件具有不可避免的噪声,串扰误差是一个重要的误差源。当同时执行多个量子操作时,由于同时操作期间门之间的串扰,量子状态可能会被破坏,从而降低电路保真度。在这项工作中,我们首先报告了几种表征串扰的协议。然后,我们从硬件和软件的角度讨论不同的串扰缓解方法。最后,我们在 IBM 量子设备上进行了串扰注入实验,并展示了使用串扰缓解方法提高的保真度。
