摘要翻译：
我们介绍了自旋链作为量子线的使用，这是最近发展成为一个有趣的话题。主要的动机是在不借助光学的情况下连接量子寄存器。自旋链是一个永久耦合的一维自旋系统。当一个量子态被放置在它的一端时，如果自旋被交换相互作用耦合，这个量子态将以某种效率动态地传输到另一端。为了达到这个目的，不需要对链体进行外部调制或测量，也许只有在末端除外。对于最简单（均匀耦合）的链和最简单的编码（单个量子比特编码），色散会降低传输质量。我们提出了各种不同的选择方案，通过自旋链来实现完美的量子态转移。最后，我们简要地讨论了这一主题发展的各个方向。

英文摘要：
We present an introductory overview of the use of spin chains as quantum wires, which has recently developed into a topic of lively interest. The principal motivation is in connecting quantum registers without resorting to optics. A spin chain is a permanently coupled 1D system of spins. When one places a quantum state on one end of it, the state will be dynamically transmitted to the other end with some efficiency if the spins are coupled by an exchange interaction. No external modulations or measurements on the body of the chain, except perhaps at the very ends, is required for this purpose. For the simplest (uniformly coupled) chain and the simplest encoding (single qubit encoding), however, dispersion reduces the quality of transfer. We present a variety of alternatives proposed by various groups to achieve perfect quantum state transfer through spin chains. We conclude with a brief discussion of the various directions in which the topic is developing.
