量子态的关联特性是量子通信和量子计算的重要资源。文章首先回顾了经典关联,量子关联的概念以及常用的度量方法,随后简要介绍了作者最近对固态格点自旋体系中量子关联的研究成果。最后对未来量子关联的研究指出了几个方向。
The conelation properties of quantum states are an important resource for quantum communication and quantum computing. In this paper, the concept and measurement of classical and quantum conelation are introduced, and some recent results of research on quantum correlation based on solid state lattice spin systems are presented. Certain interesting new research topics are pointed out in the conclusion.
