论文摘要
我们评估了小型错误校正代码的性能,我们根据具有不同的连接性和连贯性来量身定制该硬件平台:在基于Transmon Qubits的超导处理器上以及由Diamond的氮气现象中心组成的自旋量子寄存器。考虑到特定于硬件的错误和连接性,我们研究了所得逻辑错误率对平台特征的依赖性,例如本机门,本机连接,栅极时间和连贯时间。使用为给定硬件参数化的标准误差模型,我们在超导量子设备上运行代码时,通过实验结果模拟性能并基准这些预测。结果表明,对于小型代码,超导装置的准线性布局是有利的。但是,对于涉及多量控操作的代码,颜色中心的中央旋转连接可以降低错误率。
We evaluate the performance of small error-correcting codes, which we tailor to hardware platforms of very different connectivity and coherence: on a superconducting processor based on transmon qubits and a spintronic quantum register consisting of a nitrogen-vacancy center in diamond. Taking the hardware-specific errors and connectivity into account, we investigate the dependence of the resulting logical error rate on the platform features such as the native gates, native connectivity, gate times, and coherence times. Using a standard error model parameterized for the given hardware, we simulate the performance and benchmark these predictions with experimental results when running the code on the superconducting quantum device. The results indicate that for small codes, the quasi-linear layout of the superconducting device is advantageous. Yet, for codes involving multi-qubit controlled operations, the central-spin connectivity of the color centers enables lower error rates.
