局部门容错量子计算

Fault-Tolerant Quantum Computation with Local Gates

Daniel Gottesman

摘要:

我讨论如何执行容错量子计算的级联码使用本地门在小的维度数。我表明,阈值结果仍然存在于三个,两个或一个维度时,下一个最近的邻居门可用,并提出明确的建设。在二维或三维中,我还展示了最近邻门如何给出阈值结果。在所有情况下,我只是证明存在阈值,而不试图优化纠错电路或确定阈值的确切值。由于在空间和时间上的容错而产生的额外开销是每个逻辑门的错误率的多对数。

英文摘要:

I discuss how to perform fault-tolerant quantum computation with concatenated codes using local gates in small numbers of dimensions. I show that a threshold result still exists in three, two, or one dimensions when next-to-nearest-neighbor gates are available, and present explicit constructions. In two or three dimensions, I also show how nearest-neighbor gates can give a threshold result. In all cases, I simply demonstrate that a threshold exists, and do not attempt to optimize the error correction circuit or determine the exact value of the threshold. The additional overhead due to the fault-tolerance in both space and time is polylogarithmic in the error rate per logical gate.
