摘要:

量子纠错是扩大量子计算机规模的关键。宇宙射线事件通过引起芯片级灾难性错误严重影响量子计算机的运行,基本上擦除了芯片中编码的信息。在这里,我们提出了一个分布式纠错方案,通过在单独的芯片上引入额外的量子擦除纠错码层来对抗这种事件的破坏性影响。我们表明,我们的计划是容错芯片级的灾难性错误,并讨论其实验实现超导量子位微波链路。我们的分析表明,在最先进的实验中,可以将这些错误的发生率从每10秒1次抑制到每月1次以下。

英文摘要:

Quantum error correction holds the key to scaling up quantum computers. Cosmic ray events severely impact the operation of a quantum computer by causing chip-level catastrophic errors, essentially erasing the information encoded in a chip. Here, we present a distributed error correction scheme to combat the devastating effect of such events by introducing an additional layer of quantum erasure error correcting code across separate chips. We show that our scheme is fault tolerant against chip-level catastrophic errors and discuss its experimental implementation using superconducting qubits with microwave links. Our analysis shows that in state-of-the-art experiments, it is possible to suppress the rate of these errors from 1 per 10 seconds to less than 1 per month.
