论文摘要
我们提出了一个可伸缩的模拟量子模拟器，用于两个空间维度的量子电动力学（QED）。 U（1）晶格仪场理论的设置采用了种间自旋变化的碰撞，在被困在光学晶格中的超冷原子混合物中。基于先前的一维实施计划。 [1]我们为磁场设计了空间纸术语，从而解决了在较高维度中实现现实规格理论的实验实现的主要障碍。我们将我们的方法应用于纯仪表理论，并讨论量子模拟器如何描述电荷的限制现象。
We propose a scalable analog quantum simulator for quantum electrodynamics (QED) in two spatial dimensions. The setup for the U(1) lattice gauge field theory employs inter-species spin-changing collisions in an ultra-cold atomic mixture trapped in an optical lattice. Building on the previous one-dimensional implementation scheme of Ref. [1] we engineer spatial plaquette terms for magnetic fields, thus solving a major obstacle towards experimental realizations of realistic gauge theories in higher dimensions. We apply our approach to pure gauge theory and discuss how the phenomenon of confinement of electric charges can be described by the quantum simulator.
