Non-linear quantum optics based on Rydberg atoms.

该项目涉及由高激发里德堡原子之间的偶极-偶极相互作用介导的强光子相互作用的实验工作。通过测量存储为里德堡偏振子的光中的光子关联，我们可以探测里德堡介质的性质，以研究里德堡软物质的物理，并控制光子关联，以期在量子信息处理、量子计算和量子网络中应用。控制武器库中的另一个工具是微波场，它既可以改变里德堡原子之间的相互作用，又可以控制存储的光子的状态。该项目与EPSRC资助的里德堡软物质EP/M014398/1相关，其中包括与诺丁汉大学的理论合作。

The project involves experimental work on strong photon interactions mediated by dipole-dipole interaction between highly-excited Rydberg atoms. By measuring photon correlations in light stored as Rydberg polaritons we can probe the properties of the Rydberg media in order to investigate the physics of Rydberg soft matter, and control photon correlations with a view to applications in quantum information processing, quantum computing and quantum networks.An additional tool in the control armoury is a microwave field that both modifies the interactions between Rydberg atoms and controls the state of the stored photon.The project is linked to the EPSRC funded grant on Rydberg soft matter EP/M014398/1 that includes a theoretical collaboration with the University of Nottingham.
