Analysis and dissipative engineering of coherence properties of single and many-body quantum systems

近年来，在开发用于量子模拟的新技术平台方面取得了很大进展。这样的量子模拟器是一种允许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。它既可以用来探索多体物理的新元素，也可以通过将其他领域的重要问题(如数学最优化或量子化学)映射到量子系统的动力学上，我们也可以将其用作一种新形式的模拟计算机。这些技术发展中的突出挑战之一是提高我们对此类系统的控制的健壮性。还需要开发新的体系结构，其中我们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制度。在这个项目中，我们将探索新的量子模拟体系结构，基于通过测量和反馈控制微观动力学，工程多体态的耗散生产。这些都将与在基础科学水平上理解多体动力学相关，并形成用于量子模拟的新控制结构的基础。

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.
