There has been a lot of progress in recent years in developed new technological platforms for quantum simulation. Such a quantum simulator is a device that allows for unprecedented control over the microscopic dynamics of a strong interacting quantum system. This can be used both to explore new elements of many-body physics and - by mapping important problems in other fields (such as mathematical optimisation or quantum chemistry) onto the dynamics of a quantum system, we can also use this as a new form of analogue computer.One of the outstanding challenges in the development of these technologies is to improve the robustness of the control that we have over such systems. There is also a need to develop new architectures, where we make better use of classical control techniques to allow us to explore regimes that are currently inaccessible to these devices. In this project, we will explore new architectures for quantum simulation, based on controlling the microscopic dynamics through measurement and feedback, engineering dissipative production of many-body states. These will both be relevant for understanding many-body dynamics on the level of fundamental science, and form the basis for new control architectures for quantum simulation.

近年来，用于量子模拟的新技术平台的开发取得了很大进展。这种量子模拟器是一种可以对强相互作用量子系统的微观动力学进行前所未有的控制的设备。这既可以用来探索多体物理学的新元素，也可以通过将其他领域（例如数学优化或量子化学）的重要问题映射到量子系统的动力学上，我们还可以将其用作一种新形式的模拟计算机。这些技术开发中的一个突出挑战是提高我们对此类系统的控制的鲁棒性。还需要开发新的架构，更好地利用经典控制技术，使我们能够探索这些设备目前无法访问的机制。在这个项目中，我们将探索量子模拟的新架构，其基础是通过测量和反馈控制微观动力学，工程耗散产生多体状态。这些都与在基础科学层面上理解多体动力学相关，并构成量子模拟新控制架构的基础。
