量子计算机的基准测试和量子噪声的影响

Benchmarking Quantum Computers and the Impact of Quantum Noise

Salonik Resch, Ulya R. Karpuzcu

摘要:

基准测试是如何确定计算系统的性能。令人惊讶的是,即使对于经典计算机,这也不是一个简单的过程。必须选择适当的基准和指标来提取有意义的结果。不同的基准测试以不同的方式测试系统,每个单独的度量可能会或可能不会感兴趣。选择合适的方法是棘手的。对于量子计算机来说,情况更加开放,其中有更广泛的硬件,更少的既定指导方针和额外的复杂因素。值得注意的是,量子噪声会显著影响性能,并且难以准确建模。在这里,我们从计算机体系结构的角度讨论量子计算机的基准测试,并提供数值模拟,突出表明谨慎的挑战。

英文摘要:

Benchmarking is how the performance of a computing system is determined. Surprisingly, even for classical computers this is not a straightforward process. One must choose the appropriate benchmark and metrics to extract meaningful results. Different benchmarks test the system in different ways and each individual metric may or may not be of interest. Choosing the appropriate approach is tricky. The situation is even more open ended for quantum computers, where there is a wider range of hardware, fewer established guidelines, and additional complicating factors. Notably, quantum noise significantly impacts performance and is difficult to model accurately. Here, we discuss benchmarking of quantum computers from a computer architecture perspective and provide numerical simulations highlighting challenges which suggest caution.
