利用自旋链动力学产生量子态

Generating Quantum States through Spin Chain Dynamics

Alastair Kay

摘要:

通过合理选择耦合强度,自旋链可以在两端实现完美的量子态转移。在本文中,我们研究了通过设计自旋链可以创建哪些其他状态。我们的结论是,直到局域相,所有的单激发量子态的支持链的每个网站上可以创建。我们特别注意生成的W-状态,叠加在每个网站的链。

英文摘要:

Spin chains can realise perfect quantum state transfer between the two ends via judicious choice of coupling strengths. In this paper, we study what other states can be created by engineering a spin chain. We conclude that, up to local phases, all single excitation quantum states with support on every site of the chain can be created. We pay particular attention to the generation of W-states that are superposed over every site of the chain.
