项目摘要

The development of quantum simulation lacks compact on-chip scalable platforms. The recentdemonstrations of polariton lattices in semiconductor microcavities, in combination with theirextraordinary nonlinearities, place polaritons as one of the most promising candidates to achievethis goal. The aim of this proposal is to implement polariton lattices in semiconductormicrocavities as a photonic-based solid-state platform for quantum simulations. Thepolariton platform will allow for the engineering of the lattice geometry and site-to-site hoping, statepreparation and detection in individual sites, sensitivity to magnetic fields, and scalability due to thelow value of disorder. The driven-dissipative nature of the system opens the exciting possibility ofstudying out-of-equilibrium strongly correlated phases, but it also calls for new theoreticalmethods. We will combine the expertise in semiconductor physics and technology of fourexperimental groups and the input of three theoretical groups to push polariton nonlinearities intothe strongly interacting regime. We plan on implementing the first polariton simulators bystudying quantum correlations and the topological phases in flat bans and in the presenceof artificial gauge field acting on polaritons in 1D and 2D lattice geometries, bothexperimentally and theoretically. This project will provide the first quantum simulation platformusing scalable lattices at optical wavelengths.

量子模拟的发展缺乏紧凑的片上可扩展平台。最近在半导体微腔中的极化激元晶格的演示，结合它们的异常非线性，将极化激元作为实现这一目标的最有希望的候选者之一。该建议的目的是实现极化激元晶格作为一个光子为基础的量子模拟的固态平台的超导微腔。极化激元平台将允许工程的晶格几何形状和网站到网站的希望，国家准备和检测在个别网站，灵敏度磁场，和可扩展性，由于thelow值的混乱。该系统的驱动耗散性质为研究非平衡强关联相提供了令人兴奋的可能性，但它也需要新的理论方法。我们将结合联合收割机在半导体物理和四个实验组的技术专长和三个理论组的投入，推动极化激元非线性进入强相互作用机制。我们计划通过研究量子相关性和拓扑相位来实现第一个极化激元模拟器，并在一维和二维晶格几何中人工规范场作用于极化激元的情况下进行实验和理论研究。该项目将提供第一个在光波长下使用可扩展晶格的量子模拟平台。
