图-状态模型中容错性的简单证明

Simple proof of fault tolerance in the graph-state model

Panos Aliferis, Debbie W. Leung

摘要:

我们考虑量子计算的图态模型中的容错问题。利用可组合模拟的概念,我们通过调用量子线路计算的阈值定理,提供了一个简单的证明存在一个准确度阈值的图态计算。然后,在相同的噪声过程下,从电路模型中的已知边界获得图状态模型中的阈值的下限。

英文摘要:

We consider the problem of fault tolerance in the graph-state model of quantum computation. Using the notion of composable simulations, we provide a simple proof for the existence of an accuracy threshold for graph-state computation by invoking the threshold theorem derived for quantum circuit computation. Lower bounds for the threshold in the graph-state model are then obtained from known bounds in the circuit model under the same noise process.
