Quantum optics in curved space

最近，我们的团队开发了一种新的与量规无关的方法来量子化自由空间中的电磁场。这种方法已经使我们能够在非平凡的情况下重新审视场量化：例如，在量子传感应用的边界条件存在的情况下。这个博士项目的目的是建立我们目前在电磁场量化方面的专业知识，以提高我们对相对论情况下量子光学的理解。我们计划利用反映弯曲空间中电磁场丰富动力学的电场和磁场量子可观测值来获得对基础物理学的新见解，并为光子系统量子信息处理的新方法铺平道路。

Recently, our group has developed a novel gauge-independent approach to quantizing theelectromagnetic field in free space. This approach has already enabled us to revisit fieldquantisation in non-trivial situations: for example, in the presence of boundary conditions forapplication in quantum sensing. The aim of this PhD project is to build on our current expertise onthe quantisation of the electromagnetic field to improve our understanding of quantum optics inrelativistic scenarios. We plan to use electric and magnetic field quantum observables, whichreflect the rich dynamics of the electromagnetic field in curved space, to obtain new insight intofundamental physics and to pave the way for novel approaches to quantum information processingwith photonic systems.
