更经济的团簇态量子计算

Toward a more economical cluster state quantum computation

M. S. Tame, M. Paternostro, M. S. Kim, V. Vedral

摘要:

通过引入{ \it噪声团簇态}并描述其在量子计算单向模型中的作用,我们评估了团簇态中不完美的内在模型的影响。研究了单个退相通道对团簇量子比特的作用。我们表明,非理想的影响是有限的,通过使用小集群,这需要紧凑的计划进行计算。鉴于此,我们提出了一个实验上可实现的四量子比特线性簇,它模拟了受控的-{ \sf NOT}({ \sf CNOT})。

英文摘要:

We assess the effects of an intrinsic model for imperfections in cluster states by introducing {\it noisy cluster states} and characterizing their role in the one-way model for quantum computation. The action of individual dephasing channels on cluster qubits is also studied. We show that the effect of non-idealities is limited by using small clusters, which requires compact schemes for computation. In light of this, we address an experimentally realizable four-qubit linear cluster which simulates a controlled-{\sf NOT} ({\sf CNOT}).
