损失和故障容限量子计算方案中的容错和权衡

Error tolerance and tradeoffs in loss- and failure-tolerant quantum computing schemes

Peter P. Rohde, Timothy C. Ralph, William J. Munro

摘要:

量子比特丢失和量子门失效是发展可扩展量子计算的重要问题。最近已经提出了各种方案来容忍量子位丢失和门故障。这些包括基于集群和奇偶校验状态的方案。我们表明,通过设计这样的计划,专门容忍这些错误类型,我们会导致指数井喷去极化噪声。我们讨论了几个例子,并提出了最小化这个问题的技术。通常,这引入了与其他不期望的效果的折衷。在某些情况下,这是物理资源要求,而在其他情况下,这是噪声率。

英文摘要:

Qubit loss and gate failure are significant problems for the development of scalable quantum computing. Recently various schemes have been proposed for tolerating qubit loss and gate failure. These include schemes based on cluster and parity states. We show that by designing such schemes specifically to tolerate these error types we cause an exponential blow-out in depolarizing noise. We discuss several examples and propose techniques for minimizing this problem. In general this introduces a tradeoff with other undesirable effects. In some cases this is physical resource requirements, while in others it is noise rates.
