用自旋链编织分布式团簇状态梯

Knitting distributed cluster state ladders with spin chains

R. Ronke, I. D'Amico, T. P. Spiller

摘要:

自旋链在量子态传输和通信中的应用是近年来的研究热点。在这里,我们讨论利用自旋链(为完美的量子态转移而设置)编织分布式簇态结构,在链的末端重复注入和提取的自旋量子位之间。团簇态是由系统在不同激发数扇区的自然演化而产生的。我们讨论了在注入和提取过程中的错误,以及制造和随机误差的影响的消肩效应。

英文摘要:

There has been much recent study on the application of spin chains to quantum state transfer and communication. Here we discuss the utilisation of spin chains (set up for perfect quantum state transfer) for the knitting of distributed cluster state structures, between spin qubits repeatedly injected and extracted at the ends of the chain. The cluster states emerge from the natural evolution of the system across different excitation number sectors. We discuss the decohering effects of errors in the injection and extraction process as well as the effects of fabrication and random errors.
