针对容错拓扑单向计算(TOWC)，我们提出了一种可扩展的方法来构造3D簇态，即使纠缠的两量子比特门成功的概率很小。结果表明，只要两量子比特门的非先兆错误概率小于0.040%(0.016%)，就可以在两量子比特门的成功概率为0.5%(0.1%)的情况下进行容错TOWC。此外，与传统的基于概率双量子比特门的容错方案相比，该方案的资源占用得到了很大的抑制。
We propose a scalable way to construct a 3D cluster state for fault-tolerant topological one-way computation (TOWC) even if the entangling two-qubit gates succeed with a small probability. It is shown that fault-tolerant TOWC can be performed with the success probability of the two-qubit gate such as 0.5 (0.1) provided that the unheralded error probability of the two-qubit gate is less than 0.040% (0.016%). Furthermore, the resource usage is considerably suppressed compared to the conventional fault-tolerant schemes with probabilistic two-qubit gates.
