论文摘要
量子模拟器具有吸引力,是研究不适合经典数值处理的多体量子系统的一种手段。超导电路提供了用于量子模拟的多功能框架。从这个角度来看,我们讨论了超导电路如何允许各种相互作用的工程,这反过来又允许模拟各种模型的汉密尔顿人。特别是,我们专注于非线性元件介导的强光子光子相互作用。这包括晶格模型中的现场,最近的邻居和四体相互作用,从而实现了扩展的Bose-Hubbard模型和曲折代码。我们不仅在模拟量子模拟中讨论了当前状态,而且还讨论了超导量子模拟的未来观点,这些量子模拟在新兴量子计算平台中串联量子门时打开。
Quantum simulators are attractive as a means to study many-body quantum systems that are not amenable to classical numerical treatment. A versatile framework for quantum simulation is offered by superconducting circuits. In this perspective, we discuss how superconducting circuits allow the engineering of a wide variety of interactions, which in turn allows the simulation of a wide variety of model Hamiltonians. In particular we focus on strong photon-photon interactions mediated by nonlinear elements. This includes on-site, nearest-neighbour and four-body interactions in lattice models, allowing the implementation of extended Bose-Hubbard models and the toric code. We discuss not only the present state in analogue quantum simulation, but also future perspectives of superconducting quantum simulation that open up when concatenating quantum gates in emerging quantum computing platforms.
