自旋链是物理学家的理论工作，提供了一个方便，易于处理的模型，可以洞察许多物理现象，包括传导，挫折，超导性，拓扑相，局域化，相变，量子混沌甚至弦理论。然而，我们的最终目标不仅仅是了解物理系统的特性，而是为了我们自己的目的而利用它。因此，我们研究工程一类特殊的自旋链的可能性，设想这种反馈到原始物理系统的潜力。我们特别注意多体纠缠态的产生，如W（迪凯）状态，叠加在多个网站的链。
The spin chain is a theoretical work-horse of the physicist, providing a convenient, tractable model that yields insight into a host of physical phenomena including conduction, frustration, superconductivity, topological phases, localisation, phase transitions, quantum chaos and even string theory. Our ultimate aim, however, is not just to understand the properties of a physical system, but to harness it for our own ends. We therefore study the possibilities for engineering a special class of spin chain, envisaging the potential for this to feedback into the original physical systems. We pay particular attention to the generation of multipartite entangled states such as the W(Dicke) state, superposed over multiple sites of the chain.
