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

近年来，在开发新的量子模拟技术平台方面取得了很大进展。这样的量子模拟器是一种设备，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。这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模拟计算机的一种新形式。在这些技术的发展中，一个突出的挑战是提高我们对这些系统的控制的稳健性。我们还需要开发新的架构，在那里我们可以更好地利用经典的控制技术，使我们能够探索目前这些设备无法访问的政权。在本项目中，我们将探索基于通过测量和反馈控制微观动力学的量子模拟新架构，以及多体态的工程耗散产生。这些都将与在基础科学层面上理解多体动力学相关，并为量子模拟的新控制体系结构奠定基础。

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.
