AI总结:

研究在真实量子硬件上实现灯灭问题并评估Grover搜索性能,发现IBM硬件改进和IQM设备校准质量对结果影响显著。

摘要:

我们将在二维网格和Mobius阶梯图上实现灯灭问题,并在真实量子硬件上评估Grover搜索的性能。我们使用了两个实例,分别使用9个和16个量子比特,并通过IBM和IQM公开可用的量子硬件实现了它们。我们的实验显示,在IBM硬件上,Heron r1到r2代之间有所改进,突显了2023-2024期间IBM硬件的进步。灯灭电路在IQM设备上产生的输出分布接近均匀。为了诊断设备限制,我们还运行了一个小型的Grover SAT基线,发现IQM Garnet比其他测试的IQM设备更可靠。我们还观察到,相同制造修订的QPUs在性能上可以有显著差异(新设备不保证更好),并且校准对量子设备的性能有重大影响,因此设备的选择强烈依赖于校准质量。

英文摘要:

We implement the Lights Out problem on a 2D grid and on Mobius ladder graphs and evaluate the performance of Grover's search on real quantum hardware. We use two instances using 9 and 16 qubits, and implement them on publicly available quantum hardware by IBM and IQM. Our experiments show improvements in IBM hardware between the Heron r1 and Heron r2 generations, highlighting progress in IBM hardware during the 2023-2024 period. The Lights Out circuits produced output distributions close to uniform on IQM devices. To diagnose device limitations, we additionally ran a small Grover SAT baseline, finding that IQM Garnet performs more reliably than other tested IQM devices. We also observed that QPUs of the same manufacturing revision can differ significantly in performance (a newer device is not guaranteed to be better), and that calibration has a significant impact on the performance of quantum devices, so the choice of device strongly depends on calibration quality.
