论文摘要
晶格量规理论是诸如粒子物理,凝结物质或量子信息理论等不同领域的基础。人工量子系统控制的最新进展已经允许在桌面实验中研究亚伯晶格量规。但是,实现非亚伯模型仍然具有挑战性。在这里,我们采用一个连贯的量子控制方案来执行非亚伯仪表不变性,并为一维SU(2)晶格量规系统详细讨论此想法。最后,我们评论了如何将我们的方案扩展到其他非亚洲仪表对称性和较高的空间维度(总结)为非亚伯式晶格量规理论的量子模拟提供了有希望的途径。
Lattice gauge theories are fundamental to such distinct fields as particle physics, condensed matter or quantum information theory. The recent progress in the control of artificial quantum systems already allows for studying Abelian lattice gauge theories in table-top experiments. However, the realization of non-Abelian models remains challenging. Here, we employ a coherent quantum control scheme to enforce non-Abelian gauge invariance, and discuss this idea in detail for a one dimensional SU(2) lattice gauge system. Finally, we comment on how to extend our scheme to other non-Abelian gauge symmetries and higher spatial dimensions, which summarized, provides a promising route for the quantum simulation of non-Abelian lattice gauge theories.
